hi guys, I found this really usefull parts site, which has all the information on it, that the dealer has when you go in wanting parts. It is only for more modern cars, so forget about using it for CX, GS, DS etc. Basically, from BX onwards. You will need to pretend to be a company, I just put the bus company I work for in the name fields, and you too, can look up the part numbers for the stuff you need.
