friend had the 2.2 cabriolet coupe, was all good for about a year, but then things went wrong, quite badly.
alternator on his (limited edition, special edition) cost over 300 quid, and that was refurbed! steering rack went, then the pump, oil leaks, gearbox troubles, then finally went bang with no warning.
so he bought a vectra tdci, which has been off the road nearly all its 3 years of him owning it, vaux couldnt diagnose its fault which turned out to be egr valve, got that fixed and now it wont start at all, i think its the tank pump as theres no flow, but there coded pumps and not cheap.
id avoid vaux altogether
