I invested $500 in a HVLP Turbine system from TP Tools back in 1998. I've painted at least 10 cars, 2 houses, couple trailers and loads of small parts with it since then. It's portable and self contained. Can take it anywhere and paint and all you need is 110 volts to plug it into. If you are going to do just one car it's not really worth it to invest in all the equipment to setup up a conventional system. I don't even need to paint a car inside with this thing. I do it outside in the driveway on a calm day with just a canopy overhead to keep the sun off.
