Before you buy this car
From the generation guide
- Ask for proof of a timing belt change on any 16V petrol built up to 2001. No proof means budget for a belt change at once, at 260-500 EUR.
- Start the engine and check that the battery warning light goes out. A light that stays on points to a failed alternator. Ask whether it was replaced.
- Look under the car at the rear wheel arches and the front subframe mounts. Rust that has gone through the metal means a repair.
- Ask whether the EGR valve was cleaned or replaced. It often fails by about 80,000 km.
- Switch on the air conditioning and check that it blows cold. Ask whether the compressor was replaced.
- Turn the key through all positions and start the car several times. The key should turn smoothly and the car should start every time. A sticking lock or a car that will not start points to the ignition lock or immobiliser.
