// THE STORY

The first-generation Celica borrowed heavily from American muscle car styling, particularly the Mustang, and applied it to a lightweight Japanese package. The result was a car with genuine character and surprisingly good dynamics. The liftback version arrived in 1977 and became an instant classic with its fastback profile. The twin-cam 18R-G engine offered real performance for those who wanted it.

In Australia, these early Celicas are becoming increasingly rare and sought after by the JDM classic community. They were popular cars when new, but decades of daily use, modifications, and neglect have thinned the herd dramatically. Good examples are disappearing into collections. The RA28 coupe and RA40 liftback are the most desirable variants, with the twin-cam models commanding the highest prices. These cars perfectly capture the optimism and style of 1970s Japanese car design.

// KNOWN ISSUES

What to watch for.

All 18 issues

Floor Pan Corrosion

Critical
Body and Structure
What happens

Soft or thinning floors, particularly in the driver's and passenger's footwells. Wet carpet after rain. Road noise increases.

Why it happens

Water entry through deteriorated door seals, windscreen seals, and from below via road spray. The floors are better protected than British cars of the era but are not immune to 50 years of moisture exposure.

How to fix it

Weld in repair sections. Some reproduction panels are available; others must be fabricated. Cost: $500--1,500 per section.

Lower Quarter Panel Corrosion

Critical
Body and Structure
What happens

Rust and perforation in the lower rear quarter panels, behind and above the rear wheels.

Why it happens

Road spray and mud accumulate between the inner and outer panels. Trapped moisture corrodes from inside. The lower quarter area on the coupe is particularly vulnerable because the wheel arch lip traps debris.

How to fix it

Cut out and replace with new metal. Reproduction panels exist for some variants but supply is inconsistent. Custom fabrication may be required. Cost: $500--1,500 per side.

Inner Guard Corrosion

Minor
Body and Structure
What happens

Rust in the engine bay around the inner fenders and strut tower bases.

Why it happens

Road spray enters the engine bay and collects in the double-skinned areas around the inner guards. Heat cycling from the engine accelerates corrosion.

How to fix it

Clean, treat, and seal if surface rust. Cut out and fabricate if perforated. Cost: $800--2,000 per side for significant repair.

Sill Corrosion

Minor
Body and Structure
What happens

The rocker panels soften, crumble, and lose structural integrity.

Why it happens

Box-section sills trap water when drain holes block. The corrosion process is identical to that described in British cars, though the Toyota steel generally resists longer.

How to fix it

Full sill replacement. Repair panels may need to be fabricated as supply is limited. Cost: $1,000--2,500 per side.

Oil Leaks

Critical
Engine -- 18R Single-Cam
What happens

Oil seepage and dripping from the valve cover gasket, oil pan gasket, rear main seal, and timing cover.

Why it happens

Rubber and cork gaskets harden and shrink over 50 years. The 18R is not a particularly leak-prone engine when the gaskets are fresh, but all gaskets eventually fail.

How to fix it

Replace all gaskets and seals systematically. The valve cover gasket ($15--30) and oil pan gasket ($20--40) are easy. The rear main seal requires gearbox removal. Full reseal: $150--300 DIY, $500--1,000 at a workshop.

Timing Chain Noise

Critical
Engine -- 18R Single-Cam
What happens

A rattle or slapping sound from the front of the engine on cold start that may quiet as the engine warms.

Why it happens

The timing chain stretches and the tensioner wears over 150,000+ km. The chain guides can also crack and break.

How to fix it

Replace the timing chain, tensioner, and guides as a set. Cost: $150--400.
