Overview

The 1985 Toyota Supra is a sporty 2-door hatchback coupe from the second-generation Supra line (A60), positioned as a more premium, performance-focused alternative to the Celica. It’s ideal for drivers who want classic 1980s styling, rear-wheel-drive balance, and a comfortable grand touring feel with Japanese reliability fundamentals. In the 1985 market, the Supra competed with cars like the Nissan 300ZX and Mazda RX-7, offering strong practicality thanks to its hatchback cargo space. Today it’s a popular enthusiast choice for weekend cruising, light restoration builds, and period-correct performance upgrades.

Key Features

- Rear-wheel-drive (RWD) platform with a well-balanced, fun-to-drive chassis, available with a limited-slip differential on some trims for improved traction. - 2.8L inline-six engine (Toyota 5M-GE) with fuel injection, known for smooth power delivery and a classic straight-six feel; a 5-speed manual was commonly paired with it, with an automatic also available. - Four-wheel disc brakes and a sporty suspension setup for its era, delivering confident stopping power and composed highway manners. - Driver-focused interior for the mid-1980s, often featuring supportive sport seats, a comprehensive gauge layout, and available power accessories depending on trim. - Practical hatchback design with folding rear seating, making it easier to live with than many 2-seat sports cars of the same era.

Common Issues & Reliability

Shoppers researching 1985 Toyota Supra reliability often find the platform is durable when maintained, but age-related failures are common. Here are some of the most reported 1985 Toyota Supra problems and common issues: - 5M-GE head gasket failure: One of the best-known concerns. Overheating, coolant loss, milky oil, or exhaust smoke can appear, sometimes around 100,000–150,000 miles, though it can happen earlier if the cooling system is neglected. Many cars have already been repaired, but documentation matters. - Cooling system wear leading to overheating: Radiators can clog internally over decades, fan clutches weaken, and old hoses split. A marginal cooling system increases the risk of head gasket issues and can show up in traffic or hot weather. - Aging fuel injection and ignition components: Vacuum leaks, tired injectors, worn ignition wires, and failing sensors can cause rough idle, hesitation, and hard starts. At higher mileage (often 120,000+), owners may report drivability complaints that are usually fixable with methodical diagnosis. - Electrical gremlins and interior electronics: Power windows, switches, dashboard lighting, and aging grounds can become intermittent. These aren’t always expensive, but they can be time-consuming to track down, especially on unmodified cars with brittle wiring.
