A agree with the above comment but at the end of they day I think performance wise they are similar - $$$ wise they are very affordable - appearance they are very different (now at least) - feature wise, similar to an extent - and I think they do compare well based on lower $$$. They both offer great bang for buck.Originally Posted by Enigma
I think the turbo will be easier to get better performance because you just need to tweak the boost which doesn't cost that much. But the 3.2 Vectra, despite being a great drive already, will need a few grand for a supercharger or turbo, an appropriate exhaust - so there is money to spend but in the end u would have an awesome road racing sports sedan\hatch.
