Deciding between an E90 M3 and RS4
Currently I'm trying to decide between a 2008 E90 M3 Sedan and a 2007 Audi RS4. Both are similarly priced on the used market, and I cannot make up my mind.
Did any of you guys cross-shop the M3 with the RS4? I test-drove both cars and they're excellent!
I'm only looking for a manual transmission, and don't track the car, a pure daily driver, what would you guys do ?
