Hello, first of all there is a lag, and as I had never driven a turbo before I didnt know this. Also, it is not quicker than the works, even the dealer had to admit that, so dont know where you get that from! My point was that my car is faster, more fun to drive, so whats the point of changing and paying out thousands? My dealer said I can borrow the new works for a few hours when the first one arrives, have bought three minis off him and he said I can be first, but you are wrong in your assumption that the R56 is faster than Swiper!
