More great info! Thanks everyone. I have no problem going to NM or AZ if need be. I have seem a few on Craigslist today in CO with AC. As far as image, I don't really care. Most of my clients don't see my car, but if I walk in soaked after driving 2 hours with no AC, they may not be happy!
I would love a CRX, I used to have one. The only problem is I need to haul 2-3 kids a few times a week and don't want to be forced into driving my Land Cruiser.
