FYI, I think your price might be a tad optimistic. If you have time to wait, that's cool. But I'd probably lower it if you really want to get rid of it.
Damn that is a beautiful car! That is the exact color combo I was looking for when I bought my car. If I didn't already have a boxster I would be all over that car. 18,000 miles is such a low amount for a 1999. I hate to hear you're selling it, but best of luck.
