It is a 12 year old car, expect some issues------but, the pleasure of driving a Crossfire outweighs any normal service issues that crop up.
Since you are in Florida, be sure to check for flood damage. Ask the seller where he had it serviced, and use your "gut" feelings to make your decision.
If you take the plunge, utilize this forum for all its worth (priceless) to get advice and suggestions on any problems that may occur.
Also, join the Chrysler Crossfire Owners International Facebook group. You won't find a more friendly and helpful group of car "nuts" anywhere. There are also sub-groups you might consider joining also.
