don't refer back to top gear. and please don't pick another car other from those three.
i just reported people because they chose not to answer the question correctly. please pick one and explain. this isn't like oh i'll choose none, or i'll choose this and tune it up and rape it. no. answer the question. or just leave.

i would go with the RS4 although the M3 would be tempting i think you will see far more M3s on the road than RS4s plus i live in the north and the RS4 is a year round car and i would drive it year round. Im not big on garage queens.

hmm tough choice but id go with the rs4, tha thing is a monsterr

I choose none of them.

BMW. best bang for your buck and they have gotten engine of the year almost five years in a row. I don't like mercedes, they are not built like they used to be. they use cheaper parts and are overpriced. don't know too much about the audi

Assuming that you were really in the market (and I am assuming you are not) I would drive all three and choose based on personal preference.

I have never been a huge fan of the M3. Yes it's a good car, but you see them all over. It's the no-brainer choice, like the Nissan 350Z. If you actually use your brain, you might find that another vehicle suits you better.

Obviously the RS4 is immensely capable and an entertaining drive. But if you like cubic inches (and I am assuming that you do) and the newest gear, then I'm sure the C63 would float your boat the highest of all.

I would probably choose the Audi. But the others are also very fine - you know this already.

I am not a huge fan of bmw, but the m series is awesome. I would take the m3. Audi makes great cars so i would say rs4. Mercedes is straight up crap. over priced, poorly constructed crap.

ill take the bmw because they have been in the business(small fast cars) for more than 30 years.And until now it is the most sucessful road racer cars ever.BMW does what drivers want,ultimate driving machine.its a car for drivers

And what you see on top gear,the m3 is much more faster than the rivals.
