OLD style wheels on new cars doesnt look right.
My opinion shouldnt influence you anyway though. Its YOUR car and you will be driving it. If you like it, thats what matters. I put 18 inch wheels on my 70 Charger because I liked them. I get some compliments as well as some suggestions to pull them and install rallys or road wheels. I dont care. I like the car the way I built it.
