Paint set up recommendations?

I want to invest in a compressor and a paint gun etc. I have to repaint the hood, the deck lid and some other areas, but in the end I want a setup that will allow me to paint an entire car, so I don't have to upgrade at a later time. What are y'alls recommendations? CFM, HP, gallons? Models? Also paint guns?! I'd appreciate your input. Thank you.
