Jag v6 or vauxhall v6

[mrgreg]

Hi, looking at a project and the choice of drive train is either jag 3.0 v6 or vauxhall 3.0 v6 as there both rwd, will end up tuning it, just can't make my mind up which to go for ???
So thought I'd put it on here see if anyone has had anything to do with either , will be using an auto box and most of the drive train. Cheers Greg
