My car is pretty loaded and I made sure to order 18"s and I am super glad I did.
Ride quality is awesome and the fact that I can get non-rfts sealed the deal for me.
ThatKrazyPolak, not sure what your dealership is talking about. There are plenty of cars with 18s.
Here is one at my local dealership (they have at leaset 2 cars with 18s on the lot)
