2008 BMW 5 Series 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
This car handles very precisely. Engine feels like a V-8 even though it is a V6 turbo. It is scary-fast... if you are not a good driver you can get in trouble with this much speed. the interior is very comfortable -- the Premium Package seats are highly adjustable and best I have ever sat in. I previously had a 2000 528i and a 2002 X5. BMWs build quality and design is just so much better than even a few years ago. For the money, this is the best sports sedan period. Better than Lexus, Infiniti and even Mercedes that costs $10,000 more. The iDrive is a little tough to use, but if you are technologically proficient, it'll only take you a day or two to figure out.
The 20 way adjustable seats are great. Also, the iDrive offers lots of features. Bluetooth for cellphone works flawlessly - it turns radio down when a call comes in. Stereo is very good for a stock stereo -- MUCH better than prior stock stereos from even a couple of years ago.
This is a minor issue, but the turn signal stalk on the steering wheel provides no loud 'click' to indicate the turn signal has turned off. I find myself having to constantly check that turn signal has turned off. Also, the dashboard look is very spartan -- it could have smoother, warmer look.
