Craigslist is a good tool to see regional/seasonal prices and how many are on the market. Here's a shot of the current LA market. (I set max price to $25,000, highest odometer to 180,000 miles, and newest year to 2009) los angeles cars & trucks "boxster" - craigslist
Read the forum and check out the Boxster related videos on Youtube. Don't rush to buy, there are plenty on the market and there will always be a better deal next week.
This is some good stuff, thank you so much. I will definitely look into this.
