A 2.2 dti Vectra is a very poor choice, first it's a Vauxpoo and second, the cam chain has a habit of snapping, lunching the entire engine. The chain won't last past 100k and apparently it's so expensive to do, you're better off scrapping the car when it gets to time to change it. It's a known issue but Vauxpoo won't acknowledge that it should ever be replaced.
