The SRi 150 might have to go

Since the new pooch arrived it's dawned on us that the hatchback Vectra B mightn't be ideal..

So we're looking at Vectra C estates and would appreciate some input on which engine options to look for and, more importantly, which to avoid.

It won't be for a few months, we have to muster some cash, but we like to have a good ol' look around so we have a bit of a clue..

Opinions please fellow Z22SE'ers??
