When we bought the BMW X3 (our first) we were very pleased with it. As we drove it and got in and out of it, we were disappointed. They put a stupid ridge that gets in your way when you try to get out of the SUV and you have to lift your feet up or trip. Same as getting in. It's also hard to see out of when you are backing up. Too many blinded spots and the passenger's mirror moves down when you put the SUV in reverse which can cause you not to see that well. It is a stiff ride and god forbid you hit a speed bump too fast. We bought the BMW X3 for the leg room, since I'm 6'4", because I can extend my legs. Would I buy the BMW X3 again, NO.
Leg room for tall persons. Heated seats. Get up and go. Sunroof.
Remove the ridge that make it a pain to get in and out of, front and back. You shouldn't have to lift your legs that high to get in or out. Make it have more visibility when backing up. I'm 6'4" and still have a tough time seeing out when backing up. A bigger gas tank would be nice.
