I wouldn't consider this as rice, BECAUSE you don't have random stickers, decals, wings and different glowing stuff at your car.
My old Opel Corsa also only had a set of OZ rims and a stereo, which is now in my BMW ( almost to be precicse

)
I think you have to differentiate between a guy who put stuff at his car and actually thinks he will be faster with it....only because the car LOOKS faster.....or the guy like you who just wants to have a good sounding stereo instead squawking oem speakers and some nice looking rims.
and nice rims sometimes make an ugly car look good! I can tell.
btw what car does that guy drive who called your Ford rice?
