Quoted from littlecammi:To me it is Mustang over I500 over Corvette over Nascar.
This. I enjoy playing automotive themed games and Mustang is the most fun (especially a Premium/LE with the Power Shift gameplay feature) and a VERY underrated game on Pinside.
In consideration of the OP's question, I'd pick Corvette over NASCAR as I prefer its theme and more exciting gameplay.
