So given the choice Wayne you would rather drive round in a V6 vectra instead of a Golf VR or a Corrado VR 
Vectra GSI yes not a standard V6 Vectra very different cars to drive, always wanted a GSI estate but too steep on the insurance for the miles I do, I can add that I have driven both and yes I guess you could say the Golf feels more solid to drive but they don't feel quick whilst the Vectra does, it is simple, easy and in a way cheap to get the Vectra up to 220 + bhp to do the same in the Golf will be a lot more expensive also you have the worry of cam chains which are mega bucks to fix, to do the cam belt on the Vectra is around £300 tops.
Corrado VR is a different animal and prices reflect that, good ones are climbing in value but would still pick a G60 or 16V as I think they truly reflect the market that the Corrado was aimed at when it was launched.
