^^I think your wrong 250bhp is never enough, I don't know if you've drove one but they are not has fast has you'd think...Yes they are fast but when you think the old e36 M3 with the 3.2 is pushing 321 bhp and the e46 was 341bhp nearly 100bhp up on the R32??
I don't know many people who own an R32 but the ones I do, have them quite highly modified with blower or turbos pushing more than 400+bhp.
The same goes for the RS4, the 2 I have drove have been an absolute joy to drive but if your tootling along in say 4th and then plant your foot they just take an age to pick up...The R32 is not exploitable right through the rev range and is quite sluggish if caught off guard in the wrong gear.
I wait to be blown out of the water from the like of Hedge and Pomme but IMO the R and S3 will be more of a drivers car than the R32 and will also hold there money far better.
And as said the Pirelli is the car of the moment and will hold its value far better than any of the cars suggested so far.
