Used 2008 Hummer H3 for sale near Campo, CA

I was able to contact a salesman after hours by text and arrange for a viewing the next day. When I finally arrived on Saturday evening my selected vehicle was standing by for a viewing and a test drive. Afterwards we did the paperwork and I was helped by the salesman in making a domestic wire transfer through my banking app on my phone. No cash or checks necessary! Once the wire went through the service department changed the oil, detailed the vehicle and set the tire pressures. I was able to make arrangements for a delivery to my home saving me a trip and several days of anxiety. My salesman kept me informed at every step. The vehicle I chose was in great condition inside and out which speaks to the quality of the vehicles on the lot. I feel like I got quality service even though I didn’t purchase the most expensive vehicle on the lot, by a longshot. I also had the opportunity to purchase a great warranty for my vehicle, which I found to be surprising that it was available at all. I look forward to working with Kearns again in the future for my next big purchase.

I have 170,000 miles on my 2008 H3. I get about 19 to 20 MPG and it does not burn one drop of oil. The 5-cylinder engine runs great and the car performs like new. Off road, it is a beast and nothing will stop her. My wife keeps telling me to sell it and buy a newer car but I just love the way it drives and handles. I will keep this car until I am too old to be able to get into it. It has truly been a wonderful vehicle.

Brandon Johnson excellent salesman — knowledgeable, friendly, patient with all our questions, not pushy. General Manager worked with us to get the price we wanted. Comfortable showroom.

Some parts hard to find. Typical for vehicles over 10 yrs old if you insist on overpriced dealer parts. The H3 engine is the older 5 cyl Chevrolet Colorado engine & plenty of parts around for those. Some suspension & steering parts from Colorado will fit & work. Aftermarket parts quality vary from better than OEM to poor quality like all vehicles. Hummers are gas hogs including the H3. Likely you will get about 12mpg combined. The H2 is even worse. Getting through snow is a breeze but don’t try to put a snow plow on one of these. It will likely blow the undersized engine. Think of it as a plush but tough looking four banger underpowered Jeep Wrangler YJ but with an automatic, air, etc… It looks the part but is actually rather fragile. If you want tough get an H2 if you can afford the gas & can handle the size. Otherwise it may be time for a Jeep! The H3 is stylish and maneuverable. But GM cheaper out in some ways making it more of a passenger car than a truck. Maybe you want a Tahoe? They are built better. The H3 is semi collectible sort of. Few people have them. Not that many left around these days.

Great experience. Good Team and treat you right. Would buy again for sure. Great experience. Good Team and treat you right. Would buy again for sure.

It's Great. No car is perfect but this one has asked joy comfort . And dependable is to turn and doesn't slip a tire when I have to enter wooded area and hills to check cattle.

I own a H3 2008 5l and it is very easy to fix and it a strong car. You can have hundreds of ideas to upgrade and customize it.

Great experience! TC & Brianna are the best. No pressure. No sales, just serving you while you shop.

I had a great experience looking for a used Prius. I worked with David who was very knowledgeable, helpful, patient and honest. He defied the stereotype of the used car salesman in every way. Thanks so much, David!!

Great experience with these guys. They were very helpful throughout the the process. Even though we didn’t purchase the car I would definitely come back to purchase here.

Everything was as represented in the ads and in follow-up discussions. A very pleasant and knowledgeable staff.

I purchased my 2018 Ford F-150 from them recently. The truck was in great condition and came exactly as advertised. Haven't had a problem with it. Sales process was smooth and easy, and the salespeople were super professional and helpful. I would definitely consider purchasing a vehicle from them again.

Very honest and front forward. They did everything to get us a good and made the process seamless.

When looking for a reasonably priced used cars I was so excited when I ran across 518 Auto Sales and the large selection of cars they had!!! The staff including Alex, Wendy, Kyle and Scott were awesome and made me feel right at home!! I will spread the word about this place!!!

Ben and Kenny were super helpful in getting me approved and once I was approved the process was quick and easy. I will send everyone I know to them from now on.

We bought a car from them on 8/20/25 and it was a great experience. Jossue and Tim were Great people to work with. Definitely would do it again.

I had a great experience buying my car from 1A Auto Mart in Smyrna. The staff was honest, friendly, and never tried to pressure me into anything. They took the time to answer all my questions and made sure I understood everything before moving forward. The car was exactly as described, clean, and in great condition. The buying process was smooth and straightforward, and they made the paperwork easy and stress-free. You can tell they care about their customers and want you to leave happy. If you’re looking for a reliable car and a dealership you can actually trust, I highly recommend 1A Auto Mart. I would definitely buy from them again.

A very pleasant and encouraging engagement. The experience could not have been smoother. I’ll tell everyone about them.

I was a little skeptical about purchasing a vehicle I had not seen in person, the owner Michael was extremely helpful and reassured his words were honest, happy to say we are pleased with the purchase. Had this beauty shipped to Texas and it arrived in a timely manner. Definitely recommend!

This is the 3rd vehicle we have bought from Showcase auto. I am pleased with all the cars we have purchased. This time I dealt with Jesse and he did a real fine job helping us buy the car we where looking for. I will recommend them anytime someone is looking for a quality used car!

The staff were very nice and polite and kept me informed. The waiting area was very comfortable. The facility is very clean and modern. Thank you!
