The problem of owning a supercar like this vintage 1955 Mercedes Benz 300SL Roadster is that you have to take care where you drive it. No problem, if the ramp is the wrong height, lottery winner owners can pay two burly men to heft the back of this $3 million collectible into the air so it doesn't scrape the ground. Ah, the sound of money as it purrs away into the distance!
