What should I look for in a used Peugeot 307 coupe?
The 307 hasn't been as reliable as Peugeot intended and that includes the CC model. There are lots of little faults, mainly electrics-related. The folding roof mechanism comes in for its fair share of criticism, and the interior trim can also cause issues.
This is a car that makes sense to buy from dealerships before the original warranty period has expired. That way you can get them to fix any problems before you take delivery.
Most alarming are the number of recalls on the 307. Some are very serious, including one concerning potential fires in the engine bay. Make sure that all recalls have been carried out. The newer face-lifted cars from 2005 appear to be more reliable.
Service history is always important, especially on the diesel cars, so make sure a potential purchase has stamps at the correct intervals.
