Looks very 50's. A Cadilac would fit right in :) Reminds me of my favourite Dexters lab cartoon. How about adding earl and Dexters Father with a mechanical armwrestling arm. That would be fun :) It could use some personell and a bunch of truckers. Maybe put elvis somewhere eating a burger or something. Not as main focus, but somwhere in the BG as a little gag.
