The black painted 17"s i have are decent wheels.
The biggest point for keeping them is they are strong.
Lightweight wheels are either cheap and would bend way too easy. Or really expensive to be light and strong. (and then with 35 series or less tires bent or broken rims is STILL an issue.)
Then the theft problem. Great wheels are a total theft magnet. Raising the likelyhood of the car being stolen.
I personally know a guy who was carjacked FOR THE WHEELS.
Facing down a gun because some nut has the hots for your aftermarket wheels sucks.
