With regard to these comments even the trade can get caught and I repeat that too many people see full history as the bible to car buying,it is not.
I had a citroen ax recently 93 only 40k odd from new,rang previous owner and guess what--not had cambelt, easy job on it though but sold it on with that and the usual french sticking callipers.Have this laguna now rang previous owner had it for 9 years/tears
and, guess what again--no cambelt done! the clutch is high and on 130k but still no slip so just run it. Ive looked at belt seems ok so take a chance. The upshot is sometimes the maint hist cannot be got.And its how it is on the day of test/inspection that matters nothing else.
