v6 are £100 (i made a profit on the last vectra cdx £86 off egay with no interior took engine out weighed shell in and got £109) so if it pops it pops, i know of alot of cars runing it with no problems, its all down to the set up mine will be going to be set up proply once fitted, and if it was so bad vauxhall wouldnt of fitted it. based onn a difference of £0.60 its £36 a tank cheaper thats a win for me its a banger run about not a show stoper, the loon will also be going on to it but will be having sequential injection.
