My moms mini cooper did that too. When opening and closing the doors. And I have taken a 2007 Mustang GT for a spin and I have to say my 4th gen handles a hell of a lot better. Much firmer steering and control. Didn't really care for the giant turn signal lever. <I'm kinda picky on things like that, plus it was loud when it clicked, drove me nuts> The ride wasn't as smooth as my 4th gen either. And maybe its just me but I didn't think off the line that it had as much power. BTW my 4th gen is a 3.8L V6. But thats just my opinion.
