I quote directly from a colleague:
"It's the worst car i've ever had, if you so much as see me saying the word Vauxhall ever again shoot me."
He complains that the engines are underpowered, vague handling, the boot space nothing special and has had a few electrical issues.
On the basis of the strength of his recommendation I would look elsewhere.
If I was to get any car of this type second hand, SEAT Exeo. Proven reliable technology in a model that does everything right but at a lower cost.
