A friend of mine bought a Mercedes C63 for $60K flat. 451hp, 0-100km/h in 4.5 and roll-on performance that humbles all but the biggest dogs on the block. And yes, it can handle too, with limits far, far, beyond what 99.9999% of drivers could ever see on the street.
Best value in a German performance sedan, hand down. I like the 3-series a lot, but I'd have a tough time ponying up well over $60K for one when I could have had a V-8...
