* Online marketplaces: Sites like eBay Motors, Craigslist, Facebook Marketplace, and Autotrader are popular places to find used cars for sale. Be sure to carefully check seller reviews and vehicle history reports.
* Dealerships: While less likely to find a 17-year-old car on a new car dealership lot, some used car dealerships or independent dealerships specializing in classic or muscle cars might have one.
* Private sellers: Individuals selling their own cars are another common source. You might find listings through word-of-mouth, local car enthusiast groups, or classified ads.
* Auction sites: Sites like Bring a Trailer and others specializing in classic or collector cars often feature auctions for vehicles like a 2006 Mustang GT. These can be a good option, but require more careful vetting.
Remember to thoroughly inspect any vehicle before purchasing, ideally with a mechanic, and to obtain a vehicle history report (like a Carfax or AutoCheck) to uncover any potential issues.
