Well I'm an R56 S driver, and after testing several R53s and 56s I can honestly say that the R53 was more fun to drive! The supercharger was phenominally good fun, but for me (and I don't wanna offend anyone) the interior quality of the R53 was poor, mostly the indicator stalks which had no weight. Also the fuel consumption and road tax! What I will say is if u can combine the R56s quality and the R53s go kartness and supercharger, I'd be laughing. So a 1.6TSI from Mini? :)
