Flipping classic cars to earn some extra cash on the side can be a really fun and rewarding hobby. First you have to find the car to resell. So essentially you are looking for a car to buy to sell. This is a big part of the process and if you don’t buy right then all the extra work detailing and listing the car with better photos won’t make up for it.
We show you how to buy and sell classic cars online to make a profit using a step by step guide.
1. Know Your Lane Before You Start Searching
The biggest mistake new car flippers make is browsing all types of cars instead of focusing on a certain type of car. There are three things to focus on when it comes to choosing a type of car to flip.
- Budget — $2,000 “project” cars or $20,000+ turnkey classics?
- Skill level — Are you comfortable with wrenching on a car or do you look for cars that are cosmetically distressed but mechanically sound?
- Local demand — how Muscle cars are viewed in Texas versus Southern California, for example.
Focusing on a specific niche can be beneficial to a new flipper, as they will be able to quickly identify a good deal due to prior knowledge of typical retail prices for the cars in which they are interested.
2. Where to Actually Look
General marketplaces
- Facebook Marketplace — Still the single best source for underpriced classics, especially from non-enthusiast sellers (estates, inherited cars, “my dad’s old car in the garage” listings). Search broadly and set alerts for keywords.
- Craigslist — Less trafficked than it used to be, but still turns up deals, particularly in smaller metro areas where fewer flippers are watching.
- OfferUp / Marketplace apps — Worth a periodic check, though volume is lower.
Enthusiast and auction sites
- Bring a Trailer (BaT) — Great for research and comps, but competitive bidding often pushes prices to full retail. Useful more for pricing intelligence than bargain hunting.
- Hemmings — Classic car specific, tends to skew toward serious sellers and higher-quality listings.
- ClassicCars.com — High volume, good filtering tools, worth setting saved searches on.
- eBay Motors — Still active for classics, and “Buy It Now” or no-reserve auctions ending at odd hours (late night, holidays) get less bidding traffic.
Niche and local sources
- Regional Facebook groups — Search “[Make/Model] owners” or “[City] classic cars for sale.” These groups often have listings before they hit public marketplaces.
- Forums — Marque-specific forums (Mustang forums, Corvette forums, etc.) often have classifieds sections with motivated, knowledgeable sellers.
- Estate sale and auction house sites — Cars from estates are frequently underpriced because the sellers just want them gone.
3. Set Up Alerts — Don’t Rely on Manual Searching
The best deals move fast. Set up:
- Saved searches on Marketplace, ClassicCars.com and Hemmings with email/push notifications set up.
- Google Alerts for specific model + “for sale” combinations
- Regularly visit new listings within the first hour of posting to secure the best deals before other buyers snag them.
4. Learn to Spot an Underpriced Listing
Signs a listing might be a good flip opportunity:
- Bad photos — Seller likely takes similar poor photos of interior and may price car to low based on lack of marketing skills.
- Vague or short descriptions — Most non-enthusiast sellers list their vehicles for sale with descriptions like “Runs and drives, need it gone”.
- There is plenty of room for negotiation with these types of sellers.
Wrong category or misspelled model names – misclassified or wrongly spelled model names can generate less traffic and thus, may even sell for less. - Estate or inheritance language — Language from the ad that indicates the seller is an estate or is inheriting the car (e.g. “My father’s car”, “I am cleaning out the garage”, etc.). These types of sellers are generally looking to sell quickly.
- Long time on market — A car that’s been listed on the site for 60+ days is likely a great candidate for negotiation, especially if the seller appears to be open to offers and has not lowered the price recently.
5. Verify Before You Commit
A cheap classic car is not a good deal if it’s a rust bucket or has a salvage title. Before buying:
- Run the VIN through a title/history check
- Ask for a real-time video walkaround, not just static photos
- Ask specifically about rust (rockers, floor pans, trunk floor), matching numbers, and any accident history
- If it’s within driving distance, inspect in person or send a trusted mechanic — never skip this step for a car you plan to resell
6. Do the Math Before You Buy
Before pulling the trigger, run the numbers:
- Purchase price + transport + repairs/detailing + fees = your all-in cost
- Compare your total cost to recent sold comps found on Bring a Trailer, ClassicCars.com, and local sold listings.
- Be sure to include a real profit margin to compensate for your time, transport and any other unexpected repair costs.
If the numbers don’t support a fair profit after your time and expenses, look elsewhere. There are plenty of other cars out there.
Find That Classic Car!
Finding a classic car to flip online is not a matter of luck. Rather, it is a matter of consistency. While there are many smart flippers out there, they are not necessarily smarter than other individuals looking to purchase a car online. Rather, they are looking at more listings online more quickly and are experts in a particular niche. Find your niche, set up some alerts, learn the tells of an underpriced listing and make sure to do your math before you buy.
