cim easy to repair and not near 500 unless main dealer
the petrol vectras are all slow and poor on fuel
the 120 cdti is shite imo but the 150's seem to be alot better
they dont make the izuzi no more and they was shite slow and ate head gaskets and german cars such as vag are not faultless they do have rail and injector faults as do all cars.
my cdti has been faultless in the 4 yrs we have owned it never had no money spent on it other than servicing wich i do myself so just service parts oil filters ect granted shit handling and interior but engine has been faultless and i know a few people with them and theres has also been gr8
