I've had two Citroens.
An 88 F BX 19RD and a 96 P Xantia 1.9TD.
One was fantastic and never broke down, despite being a megamiler.
I say never, I had a minor alternator niggle and a hydraulic hose come loose.
One was a total and utter crock of shoite and never stopped giving me trouble, despite being owned by Citroen from new, sold through the Dealer Network with a Warranty.
