Before you buy this car
From the generation guide
- Gearbox: on a cold test drive, check for jerks in second to fourth gear, late upshifts and a hard engagement into reverse. A scanner reads fault P0700. Bad result: jerks that stay after warm-up, or P0700 in the memory. Ask for the fluid change record.
- Tyre scrub: turn the wheel to full lock at walking pace and listen and feel for a skip or judder from the outside front tyre. Bad result: a skip or judder.
