Ive just left after 3yrs working for Vauxhall...the GSI Zafira's, as mechanic28, dont seem to have any major issue's. They are mainly based on the Astra which tbh is quite a reliable car, both G and H models. Vauxhall Vectra's on the other hand never seem to be right...think the name Vectra is cursed, probably why they are scrapping it now
