definitely petrol reasons being:
-diesels are only good for low down torque top end is shite obviusly theyre are exceptions but thats wot you get with a bigger engine.
-diesels black smoke like fook and sound like tractors
-the high performance diesels cost alot eg the gold gttdi 150 is 10k plus wouldt you rather by the 1.8T?????
-petrols will always be more tunable put it this way you are never going to get a porche 911 TD
So petrol all the way,
