You'll likely find used Chrysler Crossfires ranging from a few thousand dollars for a high-mileage car in need of repair, to potentially over $20,000 for a low-mileage, well-maintained example in desirable condition.
To get a better idea of pricing in your area, I recommend checking online used car marketplaces like:
* Autotrader
* Cars.com
* eBay Motors
* Facebook Marketplace
* Craigslist
Searching these sites with "Chrysler Crossfire" will give you the most up-to-date pricing information based on your location.
