Re: Crossfire purchase??
Check out every option and button and make sure everything works -- even the seat heaters although you may not need them (hah - south FL winter nights feel mighty cold with the humidity). Take your time and try everything out. With 25k miles, you may be getting close to needing new rubber - check the tire tread and negotiate accordingly.
The price doesn't sound too out of line if it's the package and color you want. Roadsters are more popular in FL and this is the time of year to buy one. If you can keep it garaged, I suggest leaving the top down all the time to reduce wear-and-tear on the mechanism and buy an inexpensive car cover to keep the dust out.
