The BMW M3 has a very sporty appearance to it, yet it is also a very luxurious car. The reason I first bought the M3 is for the performance and the comfort of the ride. The performance is spectacular, and the ride is very smooth, comfortable, and quite. I would strongly recommend this car to people who have a lot of money to spend on a 2 door car. It is quite expensive, however it is well worth the money. I used to have a Mercedes-Benz SLK320, and I would have to say that in terms of performance, and comfort combined, that the M3 is definitely the way to go. If the M3 is a little out of your price range, I would also recommend the BMW 328CI. It is also a really nice car, very similar to the M3 comfort wise, but has lower performance. From personal experience, the car is fairly cheap to maintain, because the only time you have to take it in is for the scheduled matinence. I have never had any problems with this car, and would highly recommend it to anyone looking for the ride of their life.
