I'd keep looking. Something stock and lower mileage. How about some sort of warrantee? I'm also worried about the "new" BMW maintenance schedule. Back when you paid for service, they wanted the oil changed every 3 to 5k. Now that they have maintenance included, the oil in these turbos can go 15k miles? I don't think so. Maybe I'm wrong (and I'll assume I am) but it worries me.
