I examined all the levels of this car and found them to be vastly different in power and capabilities, yet all were well built. Now if you go out and buy the least expensive m3, it's the only one without power locks and hubcaps, well that's what you get. Fortunately if you upgrade a few thousand you get more power and amenities and the car is a different animal-= my sport hb is fast, out-handles my previous BMW 3 series and smokes my girlfriends Lexus is250 like its asleep. So if you know what you want and shop smartly you will have no regrets. Buy a base model and yes you get pinner tires and plastic hubcaps - but how can you complain its not a Ferrari when you know what you bought?
