I know there was just another rack thread...

But here's a new one anyway. What is the smallest car you have gotten away with running a moto rack on? I'm looking at ditching the truck for a small car, namely a mazda 3 hatchback. With gas supposed to go through the roof, lots of room to haul bikes doesn't do me much good if I can't afford to fill the gas tank. Obviously not an ideal setup, but unless I falls ass-backwards into a big pile of money I dont see a better option. The issue I foresee is excessive sag in the rear, which could be a good excuse for some stiff springs, maybe a sway bar while I'm at it. Anyone else running a small vehicle?
