The wheels on my Challenger are unilugs. I hate them personally, its harder to get all the lug nuts going when you take the wheels on and off. Kind of have to hold the wheel in the right spot in order to get the shanks seated right. And the washers have messed up the chrome on the rims. That being said, I bought the car with the rims on it, and haven't had any actual problems with them (other than general annoyance putting them back on). Spare lug nuts are easy to find, I had to replace a couple and got them right off the shelf at the local Napa. It can't possibly be as good as having a single pattern wheel, and with any luck I'll be rid of them soon.
