well, I agree, that using lamps instead of AO means, that you wont get the quality as you would, when using AO, but in some renders i have been able to get a very nice lighting using lamps, at least I think they're good

+ using lamps instead of AO is very usefull, if u don't want to wait like 20hrs for a very, very good render.
oh yes, maybe someone could tell me a web, that has a tutorial on modeling or/and sculpting. I would like to make my own rims or custom bumpers maybe. would be really helpfull
