* Online Classic Car Marketplaces: Websites specializing in classic car sales are your best bet. Check sites like:
* Hemmings Motor News: A long-standing and reputable source.
* ClassicCars.com: A large online marketplace.
* eBay Motors: While it has a broader selection, you can filter for specifics.
* Bring a Trailer: Known for high-quality auction-style listings.
* Specialized Forums and Clubs: Pontiac enthusiast clubs and forums often have classified sections where owners might advertise cars for sale. Searching for "Pontiac Owners Club" or similar will lead you to these communities.
* Local Classic Car Dealerships: Contact classic car dealerships in your area and surrounding regions. They may have connections to privately owned vehicles not yet listed online.
* Car Shows and Auctions: Attend classic car shows and auctions. This is a great way to see cars in person and potentially find a hidden gem.
Remember to be thorough in your searches, using variations of "1950 Pontiac Chieftain" (or other model names from that year) and "2-door sedan" in your search terms. Be prepared to potentially travel to find the right car, as these vehicles are not commonly available.
