Air Compressor Size Question, How big is big enough? Options

[BeatNavy]

This may have been covered before, but I did not find it answered explicitly:

What size air compressor is good enough for doing a decent quality paint job on our cars and otherwise work with air tools? I don't have one now, but I am thinking of making the plunge and trying to paint my car at some point. I don't think I would really do anything bigger than a 914.

Here's a more specific question: is a 60 gallon, 3HP, 11.5 CFM at 40 psi; 10.2 CFM at 90 psi good for this? There's one on CL not far from me that could be a decent deal and serve as my post-Christmas gift to myself.

The Eastwood scroll looks interesting to me, but the reviews are either good or bad. I'm going back and forth on whether to move mine or get a new one, whenever I can move.

I've got a 5hp two stage Champion with an 80 gallon tank that I got new in 1995, and it still works great, but it's noisy as a locomotive. I don't have any neighbors at the old shop, but the new one I will, so I'm exploring options, which is why I got excited about the Eastwood scroll, but it's pretty much 100% MIC which kind of scares me. My old Champion had a 5 year warranty
