My first BMW to be the last, expensive replacement parts, engine head that sits on the engine block is made of an alloy that can't be refurbished, has to be replaced with a new. When the Head goes oil seeps into the coolant ruining the coolant system. When the head is replaced the bock is damaged and has to be replaced. The bolts for mounting head onto the block often damage the block, thus making it obsolete. Read internet response to this particular model overheating. It's a shame BMW hasn't addressed the issue nor recall the poorly design Head.
The design and interior of the car.
Engine Alloy and Parts Stink!! Expensive and over-rated.
I got this car new, blue with the M sport suspension, then did a ton of mods right in the first year to make it unique and just an absolute monster in terms of HP and torque. Lowered, body kit, Dinan engine and transmission mods, Remus exhaust system, 19-inch wheels, subwoofer, bigger brakes, too many upgrades to list. I love this car, the performance is incredible, I have pegged the speedo at 155mph and driven for over an hour at 135mph with the engine staying nice and cool. The 4.4L V8 with custom exhaust has an awesome sound. Having said all that, you really need to be on top of your game keeping this car running well. You need to have a race mechanic that knows everything about BMW.

Lots of small stuff: Use metal instead of plastic in radiator tank connections, improve oil separator valve design, improve secondary air system components, improve evaporative emission system, mass air sensor design, precat O2 sensor design, camshaft VANOS control, AC final stage control unit design.
I bought my car used, 3rd owner at 108k. I drove it a year and had continuous cooling system problems. It turns out the previous owner cracked the head by overheating the car. I replaced the head myself and now the car is fantastic. You cannot have these cars serviced by the dealer, it is way too expensive. Do maintenance and repairs yourself or find a good independent mechanic, there are many. This is a great car on the highway and the handling with the sport package is exceptional. Overall the car is very well made and you can see where the money has gone to. I would highly recommend to anyone.
Handling. Good gas mileage (32 highway). Extremely comfortable. Good looking. The cupholders aren't THAT bad.
Better stereo, the bass is weak. Wish it had a more reliable cooling system.
I had owned this car for about 3 years now and it has been giving headaches with sensor lights coming on like Christmas all year round. The most common lights/failure is the odometer where ASC, ABS, Engine check lights all comes on at once. When this happens, the dealer charges an arm and a leg to have them fixed. Most time it is the stupid ASC Module that failed which is an expensive equipment to replace. BMW dealership's repair are a repair. Bunch of rip offs. They charge you by just talking to you. $140 for a scan check, then a few thousands for repairs. Don't buy these cars if you can't handle stress.
Looks good when sitting in my drive way.
Stop charging so much for parts and repairs, build parts that don't break so easily.
