You can't afford either car so keep dreaming. Too bad you don't get paid to spread the BMW gospel. LOL.There is also a video showing that the E46 beat the RS4.
Believe what you want, but a S5 will not be a competitor to the E92 M3; simple facts. It's a pig with far less HP and another diff; which will sustain more of a parasitic loss.
Your words, but every "douchebag; with 50k something can have one. It's a fast family sedan. Get real. Now the RS5 is another story, except that THAT very fast PIG will be about $15k more than the M3 and it won't be nearly as nimble.
Lastly, all Audi's typically have terrbile residuals; these cars will be more of the same. Keep kidding yourself.
