(petrolhead) stuff to do in vegas

[Luke2152]

Will be stopping in Vegas for 48 hours on my way to New Zealand around new years eve. Day 1 I want to hire a car and check out grand canyon. Pretty sure I can figure that out for myself. Then back to Vegas and tick the tourist boxes. Just wondering if there's anything automotive wise worth checking out - museums, shops with shiny go fast stuff or motorsport to watch. Not planning on any of the 'drive an indy car for 2 minutes' type experiences unless they are truly awesome and sensibly priced.
