The Bay Area is a great hunting ground for 2002's. So is southern California. Good luck! Talk to and meet up with some of your local 2002 owners... They will be happy to help you.
Colors: People are nutso for Inka and a few other paint codes. Easier to buy and plentiful: Chamonix, Malaga, Sahara, Siennabraun, Polaris, etc.
My first 2002 was found in northern Alabama. It was sold new in Montgomery, AL. Very little rust. It was tired, yet complete. It needed brakes very badly. Then it needed an exhaust manifold, a shifter rebuild, lots of hoses and belts, a clutch, a guibo, shocks,struts, etc. However, there was very little down time. It was 'Okay" once the brakes were redone. I had a great learning experience and a lot of fun. My current 2002 was sold new in Austin, TX and spent most of its 'life' in Texas. I bought it last June.
Besides the advice you have already received, be a good judge of the seller. I have found that if I am comfortable with the seller, things work out fine. If something is a bit off, I won't buy the car.
I am including a photo of me as the newb in 2004:
