Before you buy this car
From the generation guide
- Press the brake pedal at a standstill. It should feel firm and not move sideways. Bad: a hard or loose pedal, or no record of the brake-pedal campaign.
- Ask for proof that the air conditioning drain-hose campaign was done. Run the A/C and check that it cools and the car starts without warnings. Bad: no proof, or electrical warnings. Needs a scanner for electrical fault memory.
- Look around the turbocharger and its feed pipe for oil. Bad: oil on the turbo or its pipe.
- Check the ISOFIX (child seat anchor) brackets on the rear seats, and ask for proof of the campaign on cars built in 2020. Bad: no proof for a car built July to September 2020.
