Yeah ive heard about the 530d's and 535d's. a guy I know has one and I didnt even know they were twin turbo aswell.
The Guy in the 530d the other night couldnt have been giving it all as I left it too easy, when I spoke to him at the set of lights and I asked him what he had and he told me, I said "ah ok then ill let you go first, no point in me holding you back" he replied "no ill stay behind you and you go, your car is fast man" lol.....must have been a right foot virgin because ive seen these Bimma's fly before!
