i always have wondered this about lifts...doesn't the dirt and fluids etc that fall off the upper vehicle drip on the lower vehicle??
and don't some of those fluids da mage paint?
My 2-pole lift has a solid metal floor (3 removable panels). No drips or leaks from my NSX, but these panels would handle such. I always park my daily beater (RL / ES300) under with no problems. I think the NSX know it's above all the other cars.
