"High end" car owners are just blowing money, IMO..... I'll put my shine up against any... Mother's has served me very well for a lot of years. I guess even after I started making good money I just never got the Yuppie mentality. I know that you don't have to spend a bunch to make paint shine. (If it's a good paint job)
Maybe that's why in 2006 I'm retiring @ 55 years old.
Lastly... Like I've said before..... Use the wax that you're most comfortable with. Just don't say that because a product doesn't cost a bundle that it can't be any good. Because when you make that statement you're dead wrong.
