Welcome. Keep a eye on CL, i'm sure you'll find one. Socal, rust should'nt be a issue in your area. Good luck with your search!
Whats the most miles you are willing to take? When I was looking I only wanted one under 125k miles but when I test drove the one I have now at 166k miles and it drove like a gem thats why I got it. Plan to go on a 2000 mile roadtrip next week.
