I know this is a ripoff idea, but...
Wouldn't it be cool for the car reviews if you could run each car you review through a lap at the ocala kart track, and keep tabs on their lap times with a leaderboard. You could have some basic atmospheric info (temp, precipitation), lap time, and stock class, and make it publicly available.
It would be like a more advanced version of Top Gear's test runs, but for AutoX speeds.
