* Online marketplaces: Websites like eBay Motors, Craigslist, and Facebook Marketplace often have listings for used Hummer H1s. However, be very careful and thoroughly vet any seller before committing to a purchase.
* Used car dealerships: Some larger dealerships specializing in classic or luxury vehicles might have a Hummer H1 in stock, but this is less common.
* Specialized Hummer dealers (rare): While not abundant, there might be dealerships that specialize in Hummers or military vehicles. You'd likely have to search specifically for these.
* Private sellers: Individuals selling their own Hummer H1s are a possibility, but again, thorough due diligence is crucial.
Keep in mind that because they are discontinued and highly specialized vehicles, finding a Hummer H1 for sale can take time and effort, and they'll likely command a high price. Expect significant maintenance costs as well due to their age and mechanical complexity.
