Just watch the heads in them because they had a recall in the early ones for I think burning up the valves. Parts are expensive but they're worth it. From a dig, they're not necessarily insane. Not really what it is built for. But, punch it in one of those from a roll even in stock form and I think you will be pleasantly surprised. Just get it checked out because a lot of them get ragged out. I am looking at selling my car for an 05 M3 ZCP (Competition Package). Would love to have ya as part of the Bimmer family though! Once you do it, you'll never go back.
