To find one now, you'll need to look at the used car market:
* Online marketplaces: Websites like Craigslist, Facebook Marketplace, Autotrader, and Cars.com are good places to start your search. Be sure to specify "Chevrolet S10 Extreme" in your search terms.
* Dealerships: While less likely to have one on their lot, some used car dealerships might have a used S10 Extreme. You could call dealerships in your area and inquire.
Keep in mind that finding a well-maintained S10 Extreme will likely require some searching, as they are now quite old. Expect to pay a price reflecting its age and condition.
