What is the difference between a Midget and an Austin-Healey Sprite?

From 1961 to 1971, the MG Midget and Austin-Healey Sprite were the same car with different badges. They shared the same body, engines, gearboxes, suspension, and interior -- the only differences were the grille design, badging, and minor trim details. Parts are fully interchangeable between the two.

The MG badge carried more prestige in export markets, so the Midget generally sold in larger numbers. The Sprite was discontinued in 1971 when Donald Healey's licensing agreement with BMC expired. After that, only the Midget name continued.

When buying, treat Sprite and Midget as identical. A Sprite in better condition is always a better buy than a Midget in worse condition. Prices are similar, though early Sprites (particularly the Mk1 "Frogeye" from 1958--1961, which predated the Midget entirely) command a significant premium.

Which Midget should I buy?

The 1275cc Mk3 (1966--1974) is the best Midget for most buyers. It has the sweetest engine (the 1275 A-series is a gem), the most developed chassis, and the best balance of power, reliability, and character. Chrome bumper Mk3s are the most desirable.

The Mk1 and Mk2 are more collectible but less practical -- smaller engines, earlier technology, and higher prices for equivalent condition.

The 1500 (1974--1979) is the cheapest Midget to buy and has a reputation for crankshaft failure that depresses values. If budget is paramount, a 1500 is still a Midget and still fun -- just treat the engine gently and change the oil religiously.

Will I fit in a Midget?

Maybe. The Midget is genuinely tiny. The cockpit is significantly smaller than the MGB. As a general guide:

• Under 175 cm (5'9"): You will fit fine and be comfortable.
• 175--183 cm (5'9"--6'0"): You will fit but may find the legroom tight and the hood (when up) close to your head.
• Over 183 cm (6'0"): You may struggle. Sit in the car before buying -- try it with the hood up, operate all the controls, and check that you can see over the windscreen frame.

Wide-shouldered people may also find the cockpit restrictive, as there is minimal elbow room. The Midget is a car that rewards smaller drivers -- it was designed in an era when people were, on average, shorter and slimmer than today.

How fast is a Midget?

Not very, by modern standards. The 1275 Mk3 does 0--60 mph in about 13 seconds and tops out at around 150 km/h. The 1500 is marginally faster in a straight line but feels less eager.

Speed is not the point. The Midget weighs 750 kg and sits very low to the ground. At 80 km/h, it feels fast because the ground is rushing past just centimetres below you, the wind is in your hair, and every input translates directly into a response. The Midget is about sensation, not velocity. On a twisty backroad, it is as entertaining as cars with three times its power.

Is the 1500 engine really unreliable?

The 1500's reputation for crankshaft failure is partially deserved but somewhat overstated. Thousands of 1500 Midgets ran without problems for their entire lives. The issue is that the big-end bearing journals are marginally sized, and the engine is less tolerant of abuse than the A-series it replaced.

If you own or buy a 1500: change the oil every 5,000 km without fail, avoid sustained high-RPM driving (don't hold the engine at redline for extended periods), keep the cooling system in excellent condition (overheating accelerates bearing wear), and monitor oil pressure. A well-maintained 1500 will provide years of reliable service. A neglected one is at genuine risk of catastrophic failure.

The A-series 1275, by comparison, is essentially indestructible. If you have the choice and the budget, the 1275 is the safer bet.

What is crankshaft end-float and why does it matter?

Crankshaft end-float is the amount of fore-and-aft movement in the crankshaft, controlled by thrust washers. On the A-series engine, the specification is 0.05--0.13mm. As the thrust washers wear, the end-float increases. Excessive end-float (above 0.25mm) allows the crankshaft to move back and forth enough to wear the rear main bearing housing, eventually causing oil pressure loss and catastrophic failure.

This is the A-series engine's most critical failure mode. It is caused by riding the clutch (keeping it partially engaged in traffic), which puts axial load on the thrust washers. The cure is to check end-float regularly (a simple measurement with a dial indicator), avoid riding the clutch, and replace the thrust washers during any engine rebuild.

Check end-float on any A-series Midget you are considering buying. It is a 10-minute test that tells you more about the engine's health than almost any other single measurement.

Can I daily drive a Midget?

You can, but you probably shouldn't. The Midget is a pure fair-weather sports car. It has no air conditioning, minimal weather protection (even with a good hood), no power steering, basic brakes, and a cockpit that makes long commutes exhausting. In heavy traffic, the tiny car feels vulnerable next to modern SUVs.

The ideal use case is a weekend car and sunny-day commuter. Keep it for drives where the enjoyment of the car is the point, not just getting from A to B. Many Australian Midget owners use them as second cars, driving them when the weather is good and the route is interesting.

If you must daily drive one: fit electronic ignition, upgrade the cooling system, carry spares, and have a backup plan for rainy days.

Are parts available?

Yes, and the supply is good. The Midget shares its A-series engine with the Mini, Morris Minor, Austin 1100, and many other BMC cars -- the parts base for A-series engines is enormous. Body panels, suspension components, brake parts, and electrical items are all available through specialists like Moss Motors, Brown & Gammons, and Australian British car specialists.

The 1500 engine parts come from the Triumph Spitfire supply chain, which is also well-served.

Body panels are the easiest items to source -- replacement wings, sill sections, floor pans, and repair panels are all available off the shelf. The Midget's parts supply is not quite as comprehensive as the MGB's (the MGB sold in larger numbers), but you are unlikely to be stuck waiting for an unobtainable part.

How does the Midget compare to the MGB?

The Midget is smaller, lighter, cheaper, and less powerful. The MGB is more comfortable, more refined, faster, and more practical. The two cars share the same basic British Leyland DNA but are aimed at different drivers.

The Midget is the purer driving experience -- lighter, more responsive, and more connected. At low speeds on a twisty road, the Midget is arguably more fun than the MGB because it demands more skill and rewards finesse. The MGB is the better all-rounder -- more comfortable for longer drives, more practical (especially the GT), and more relaxed at highway speeds.

Choose the Midget if driving fun is your top priority and you don't need to carry anything larger than a small bag. Choose the MGB if you want a more versatile, more comfortable, and more usable classic sports car.

What engine oil should I use?

20W-50 mineral oil for all variants. The A-series and Triumph 1500 were designed for mineral oil. Synthetic oils are unnecessary and can leak through old gaskets.

Oil capacity: approximately 3.4 litres (A-series) or 3.7 litres (1500) including filter. Change every 5,000 km or 6 months. Use a quality filter.

Should I fit electronic ignition?

Absolutely. An electronic ignition conversion ($80--130) replaces the contact breaker points and condenser with a solid-state trigger. It fits inside the existing distributor and is invisible. The benefits -- no more points adjustment, no more condenser failures, better cold starting, more consistent timing -- make it the best single upgrade you can make.

How much does a Midget cost to maintain per year?

For a well-sorted car maintained by the owner: $1,000--2,000 per year. This covers oil changes ($25--40 every 5,000 km), annual service ($60--120 in parts), minor repairs ($100--300), and registration/insurance ($400--800).

Professional servicing doubles those figures. The first year of ownership typically costs an additional $1,000--3,000 for initial sorting -- cooling system, suspension refresh, and addressing deferred maintenance.

Can I tow anything with a Midget?

No. Well, technically you could tow a very light trailer, but the Midget's 750 kg kerb weight, live rear axle, and modest brakes make it entirely unsuitable for towing. The car struggles enough carrying two adults and their luggage. Leave the towing to something else.

What are the most common modifications?

Popular Midget modifications include:

• Electronic ignition: The number one modification. Cheap, invisible, transformative for reliability.
• Telescopic shock absorber conversion: Replaces the original lever-arm dampers with modern telescopic units. Dramatically improves ride control. $150--300 per set.
• Aluminium radiator: Better cooling for Australian conditions. $200--400.
• Parabolic leaf springs: Smoother ride, less axle tramp. $400--700.
• Weber DCOE carburettors: The classic performance upgrade. Twin 40 DCOEs on a proper manifold can add 20--30 hp. $800--1,500 complete.
• 5-speed gearbox conversion: Using a Ford Type 9 or Mazda gearbox. Adds an overdrive 5th gear for relaxed cruising. $1,000--2,000 complete.
• 1275 engine swap (into a 1500 car): The ultimate upgrade for 1500 owners who want the A-series character. Requires engine, gearbox, and various ancillaries. $2,000--4,000.

Is the Midget a good first classic car?

The Midget is arguably the best first classic car you can buy. It is mechanically simple enough for a novice to learn on, small enough to work on in a single-car garage, cheap enough that mistakes are not financially devastating, and well-supported enough that help is always available.

The A-series engine is one of the most-documented engines in automotive history -- workshop manuals, forum posts, YouTube videos, and experienced club members can guide you through any repair. The car teaches you about points ignition, SU carburettors, leaf springs, drum brakes, and all the fundamentals of classic car mechanics.

Buy a 1275 Mk3 in the best condition you can afford, join the MG Car Club, and start learning. You will make mistakes, you will get oily, and you will have the time of your life.

How does it compare to a Triumph Spitfire?

The Midget and Spitfire were direct competitors from 1962 to 1979. The Spitfire is a prettier car (that Michelotti body is stunning), has more cockpit room, and a swing-axle rear suspension that gives it notorious handling at the limit. The Midget is more honest to drive -- the live rear axle is agricultural but predictable, while the Spitfire's swing axles can cause sudden oversteer that catches out the unwary.

The Spitfire's body rots less than the Midget's (it uses a separate chassis), but the chassis itself can corrode. Parts availability is similar for both. The Midget has a larger and more active club community in Australia.

On a twisty road driven within its limits, the Spitfire is the prettier car to arrive in. The Midget is the more entertaining car to arrive in.

What about the Frogeye Sprite?

The Austin-Healey Sprite Mk1 "Frogeye" (1958--1961) is a separate car from the Midget, produced before the Midget badge existed. It uses a different body with its iconic bug-eyed headlamp pods, a simpler chassis, and quarter-elliptic rear springs. Frogeyes are highly collectible and significantly more expensive than equivalent Midgets -- clean examples start at $25,000 AUD and excellent restorations reach $40,000--60,000.

If you love the Frogeye's looks and can afford the premium, it is a wonderful car. But the later Mk3 Midget is the better car to drive -- more powerful, better-braking, and more refined.
