Any GM product. Although, having NEVER been a Corvette fan, I do have to admit that the new Z06 is finally looking like a nice sports car. Plus, the performance is finally there where a sports car should be.
That Aztek is up there on my list too. But so is the Honda Ridgeline (and the strikingly similar looking american pickup - can't remember which one.) Oh - and that squat, out of proportion looking 2 door Mercedes that came out I think in the late 90's? And so is just about any "economy" car. I never could understand why economy cars always have to look so bland and stupid. It doesn't take an expensive, "creative" design person to come up with a halfway decent looking body style. Oh yeah - Lamborghinis. Always have, always will, except for maybe the first generation Countach without all the extra bumpy crap.
