Why shouldn't I trade in the EVO for a 335?

No, you pay on the difference between trade in and the purchase price.

Your new shit is nice, and the price you got it at was great. Had I seen it I would have scooped it up as well…but that’s a great setup at a decent price. Not a lot of those around.

Exactly, for a while I thought about selling the EVO and getting an M5 but w/ the 335 out now power + BMW warranty coverage = the win.
