I checked KBB.com, and a used price to buy from a dealer would be about 47-50k for a lightly optioned 750i.
I personally avoid first model year cars, but your money, buyer beware. Unless it was bought late 2008 as a 2009 model, you should still have a little warranty left. Id take it to a dealership and have them check it out.
As far as the transmission jerking, are you referring to your 650 coupe or a 7? I don't get that feeling at all from mine.
