How much does a Volvo 122S cost?

You'll find clean running examples from $600 to several thousand depending on condition. The sweet spot is around $3,000-8,000 for a solid driver. Rust-free survivors command a premium, especially late-model 122S two-doors with the B20 engine. Don't expect a bargain for a showroom car. A $1,000 122 exists, but it'll need work. Budget realistically: if the price seems too good, you're buying someone else's rust repair bill.

What engine should I look for?

The B20 is the one you want. More torque, more power, and still dead reliable. The earlier B18A is slower and frankly gutless on the motorway. If you're lucky enough to find a B20E (fuel injection), grab it, best performance of the lot. The B18 will run forever, but overtaking is painful. For a daily driver, hold out for the B20.

Is the 122S reliable enough to daily drive?

Yes, absolutely. These cars were built to last 300,000km minimum. The seats are brilliant, there's loads of room, and the dual-circuit brakes are far safer than an Amazon. You're not buying it for speed, it's heavy and leisurely, but it'll get you there every single time. Keep up with maintenance and you'll have a car that outlasts its Japanese contemporaries by a decade. Rust will kill the body long before the mechanicals give up.

What are the common rust spots?

The usual suspects: sills, wheel arches, floors, and spare wheel well. Sills are three-piece construction, if one's gone, they're all suspect. Check above the sills where the front wings meet the body. The front wings rust above the headlights and behind the indicator lights (pre-1977 models especially). Battery box, firewall, chassis legs, door bottoms, all need inspection. Late-model 122s (post-1988) had better rust protection, but most survivors are earlier cars. Rust repair is DIY-friendly if you can weld, expensive if you can't.

Where do I find parts?

IPD and FCP Euro. Both specialise in classic Volvos and ship quickly. You'll get OEM-quality filters, gaskets, and wear items far cheaper than your local auto parts store. eBay works for body panels and trim. Don't bother with Amazon for Volvo-specific bits, the quality's hit-and-miss. The 122 shares loads of parts with the 140 and 1800, so availability is excellent. Panels are still reproduced. Sills, wings, floors, all available and cheap.

What should I check when buying?

Rust first, then mechanicals. Crawl underneath with a torch and a magnet. Check sills, floors, chassis legs, jacking points, spare wheel well. Poke the door bottoms and wheel arches. Look for bodge repairs and filler. Check the windscreen and rear glass for white fog, that's moisture ingress from rust or bad seals.

Test the brakes hard. Listen for knocking from front suspension (worn bushings, ball joints). Check for oil leaks at the rear main seal, the PCV system clogs and pressurises the crankcase. Ask if the PCV was serviced. It's not a simple valve like a Japanese car; it's a whole system. If neglected, it'll blow the rear main seal.

Can I use it in winter?

Not recommended. Road salt will accelerate rust dramatically. These cars have decent heater cores and handle cold starts fine (especially the B20), but the bodywork won't survive salted roads unless you're fanatical about washing. If it's your only car and you live somewhere with harsh winters, budget for serious rust repairs or find a galvanised later model.

What's the fuel consumption like?

Expect around 10-12L/100km (23-28 mpg) mixed driving with the B20. The B18 is slightly thriftier but not enough to matter. The B20E with injection is the most efficient. Don't buy a 122 expecting economy, you're buying it because it's brilliant to drive and built like a tank.

Are manuals better than automatics?

Skip the auto. The manual gearbox is far more engaging and the auto saps what little power these engines make. The four-speed manual is tough as old boots. If you find a clean 122 with an auto and you're not fussed about performance, it'll be reliable enough, but honestly, don't bother with the auto.

What about parts availability for the B18 vs B20?

Both are well supported, the B-series four-cylinder ran for decades across multiple Volvo models. Gaskets, bearings, pistons, rings, all available. The B20 shares parts with the 140 and 1800, so you've got a huge aftermarket. Don't let engine choice dictate the purchase if the body's solid. You can always swap a B20 in later.

Is it good for a first classic car?

Absolutely. Simple mechanicals, loads of online support, cheap parts, and easy to work on. The 122 is far more DIY-friendly than modern cars. You don't need specialised tools for most jobs, a decent socket set, jack stands, and a workshop manual will get you through 90% of maintenance. The community is helpful and there's decades of forum knowledge. Just budget for rust repair if you can't weld.

What's the deal with the PCV system?

The 122's PCV system is more complex than a simple valve. If it clogs, it pressurises the crankcase and blows the rear main seal. Check that it holds vacuum, rubber glove test through the oil filler. If it doesn't, replace the whole system before it grenades your seals. It's a fiddly job but totally DIY-able. Don't ignore this, it'll cost you big money if the rear main goes.

What's the best 122S variant?

Late-model 122S two-door with the B20. Best performance, best looks, best driving experience. The four-door 122 is more practical but the two-door is the one to have. If you can find a rare 123GT, buy it immediately. Station wagons (the 221/222) are brilliant if you need space but command less money because they're less desirable. For a driver, find the cleanest B20-powered car you can afford and don't worry about spec.

How's the handling?

Solid, predictable, not exciting. The 122 understeers gently and the ride is firm but comfortable. Handling is old-school, it's not a sports car. The steering's direct enough and the brakes are excellent for the era (dual circuit, remember). You're buying a 122 for character and durability, not lap times. It's fun in a different way, proper mechanical involvement.

What about insurance?

Classic car insurance is generally cheap if you're over 25 and the car's not your daily. Shop around for agreed-value policies. If you're using it as a daily, standard insurance applies and premiums vary wildly by region and age. The 122's safe, slow, and simple, insurers don't hate them.

What oil and fluids should I use?

Engine oil

20W-50 mineral oil is the correct choice for Australian conditions. The B18 and B20 were designed for heavier-weight mineral oils and have larger bearing clearances than modern engines. Valvoline VR1, Penrite HPR 30 (20W-60), or Castrol Classic 20W-50 are all proven options.

In cooler climates or for winter starts, 15W-40 mineral or semi-synthetic is acceptable. Avoid full synthetic oils, they can cause leaks past old seals and gaskets that have set to the mineral oil profile over decades. If you've rebuilt the engine with new seals throughout, a 15W-40 semi-synthetic is fine.

Change interval: Every 5,000 km or 6 months, whichever comes first. These engines don't have modern filtration, so short intervals matter. Use a quality filter (Mann, Mahle, or Ryco).

Gearbox oil

Manual (M40/M41): SAE 30 engine oil or ATF Type A/Dexron II. Volvo originally specified engine oil for these gearboxes. Do not use GL-5 gear oil, it attacks the brass synchro rings and will destroy them. GL-4 80W is acceptable if you prefer gear oil, but many owners run ATF for smoother shifting in cold weather. Top up via the fill plug on the side of the box, oil should be level with the bottom of the plug hole.

Automatic (BW35): Dexron II or Dexron III ATF. Check with the engine running at operating temperature, dipstick on the side of the box. Overfilling causes foaming and harsh shifts.

Overdrive (Laycock J or D type): Shares oil with the main gearbox. If shifting is sluggish, check the oil level first, the overdrive is the first thing to suffer when it's low.

Differential

SAE 90 GL-4 or 80W-90 GL-5 hypoid gear oil. The rear axle uses hypoid gears, so GL-5 is acceptable here (unlike the gearbox). Penrite Pro Gear 80W-90 or Nulon 80W-90 are good options. Fill to the bottom of the filler plug hole. Change every 40,000 km or if the oil comes out grey or metallic.

Coolant

Ethylene glycol-based coolant mixed 50/50 with distilled water. Nulon Long Life or Penrite Green are both fine. Do not use tap water, the minerals accelerate corrosion in the block and radiator. The B18/B20 cooling system is all-metal (no plastic), so traditional green coolant is perfectly acceptable. Flush and replace every two years.

Brake fluid

DOT 4. Penrite Super DOT 4 or Castrol DOT 4 are widely available. DOT 4 has a higher boiling point than DOT 3, which matters on a car with front discs that can get hot in traffic. Bleed and replace every two years, old fluid absorbs moisture and reduces stopping power. If the fluid looks dark brown or black, it's well overdue.

Power steering

The 122S does not have power steering from the factory. If it's been retrofitted (uncommon), use Dexron II/III ATF.

Greasing

Don't forget the chassis. The 122S has multiple grease nipples on the front suspension (ball joints, kingpins, steering linkage) and the propshaft universal joints. Use a quality lithium-based chassis grease and hit every nipple at every service. Neglecting the grease gun is the number-one cause of premature suspension wear on these cars.
