Disregard this man immediately, the C63 and RS4 particularly sound awesome.
Ive tried most of these as I was in a similar position a while back. The RS4 isnt particularly exciting but is very nice looking and the estate is practical, the C63 is really good but very, very juicy and the M3 handles better ......... but then Lexus IS-F feels more special and the XFR is probably the best car, but I still cant help feeling its one for my Dad.
It would be close between the Lexus and the BMW for me, Id probably go Lexus after much consideration. If I didnt care about corners Id buy a full fat Range Rover
Ive not tried a Stang but if it comes close to any of the above in terms of quality, dynamics and design Ill eat my trousers.
Sorry oh holy one full of all knowledge i forgot how your your opinion is the only right one
