Great Performance Sport Sedan
 This car performs amazingly well given the facts that is a heavy midsize sedan.  The look is great! Definitely a head turner with the Sport package.  If you are looking for gas mileage stay away from the V8 but if you are mostly looking for performance and power, this is definitely the car for you.  I have owned different cars, but this car is very special.  You feel in control and you feel like you own the road when you are driving it.  It is definitely a joy.  I have owned the car for about 2 years now and I bought it with 73,000 miles.  Currently at 104,000 miles and no major problems so far.  The only major issues was resolved under warranty after a few days I bought the car at the BMW dealer it had an oil leak and a rattle in the engine but they fixed it. Also the car's transmission would malfunction sometimes but they reprogrammed the computer and the problem was gone.  Other little things that I have done myself are the angel lights that went out, fog lights, brakes, etc.  Something that does bother me is the transmission at low speed, it is a bit jerky especially when you drive it first time during the day.  I've been thinking about upgrading to the F10 version but reading about all the mechanical issues they have, I think I'm sticking with this one for now since it has been such a great car so far.
