2-3k? I paid 8k for my upgrade (if the missus is reading, that was 3k, I'm just exageratting for the guys)
I can see the attraction in making your car look a bit different from the norm by having a bit of bling around your wheels, but I feel you'd be destroying the spirit behind personalizing your car, because your cheapening it with mock-ups instead of the real thing. And seriously, if you've already put some time and effort into making your car gleam like I see in your avatar, I don't think you'd be truly happy cruising in those cheap things.
At least that's my 2 cents
