If I was a LHS I would be flogging car kits off as cheap as I could, get as many sales as possible, because the money you "lost" (or should I say didn't make) would be easily made up in spares, tyres, upgrades etc.. If you mananged to flog off the same model car you could have a massive range of spares *in stock*..
I do not know what wholesale prices are like though...
