Thanks everyone.
So if I'm shopping, how do I tell what the build date is on the 2011s? (Something with the VIN?) My F10 has the newer combox features that you mentioned and they are nice, though perhaps not a must have.
1FastX5, that looks like an incredibly impressive rig, but I doubt I could afford something like that. Or rather I could, but after I give it to my wife in a few months, I wouldn't be able to get as nice of a sports car for myself.
Also, I worry that a highly modded car would be more likely to have problems, whether that worry is valid or not.
