My Dad reports exhaust has failed on his 02 Xsara HDi 90 - gone either side of the cat at the front. New section? £250
Slightly worried, I looked up the price for the equivalent piece on my Xantia HDi 110. £360
So, if you are looking to buy an HDi, make sure you look underneath at the state of the exhaust, and deduct a suitable amount from the asking price if the exhaust is looking duff
