Newbie Question
 

Sorry if I'm posting this in the wrong area. I've been admiring the Mini for quite a while now and I'm finally ready to pull the trigger. I've been looking for something with good mpg and that is fun to drive, with a decent amount of cargo space (once the seats are folded). My question is, what are the main differences between the Cooper and the S, besides the supercharger? Suspension? Stiffened chasis? If a base cooper is blown, does it have the identical engine as the S, or are there other engine upgrades? I'm assuming the fuel system is upgraded, but I'm more concerned with the engine internals. How much boost does the stock blower put out? Any other comments or opinions about the Mini experience would be great. Thanks for the help guys!
