Used GMC Sierra 3500 trucks for sale near Bethany, OR

I bought a 2023 Grand Wagoneer from this store in December. They were FANTASTIC! And we love our New Jeep Grand Wagoneer. Tate was a great salesperson.

Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Great service. Everyone were so pleasant and very helpful in my first car maintenance. Thank you for all you do.

Nice staff and the salesman was both professional and personable. Explained everything that I ask about. I found another certified Manx vehicle at Mecum and purchased. Again, thank you.

Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!

The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

The car I wanted at a price that I would pay. Doug is very personable. Nice neighborhood.

great truck and lots of upgrades. Low mikes and only 2 owners. It is ready to pull your s=car trailer, 5th wheel or pull behind RV.

I was looking at a 2015 Ford F-150 that they had listed on their website. I made an appointment with Alec and came in the next day to look at it. He and the team at Gladstone Mitsubishi made sure that all my needs were met and I was happy. The buying process was very smooth and easy. I didn't feel forced or pressured like at the other dealerships I visited prior! Loved the team and hospitality provided.

I brought my SUV in for a repair on 11/19/24. Josh Baldwin, the service manager, was very proactive communicating with me via text on the diagnosis, estimated cost to repair, and estimated time to repair. Their technician made a video showing and explaining where the problem was and what was needed to fix it. Their entire service process felt open and honest, unlike other dealers' service departments I've dealt with.

Kudos to Keny an JR for the friendly attention. Walked out with a good deal. Mahalo!

Lane Departure saved me on a few long trips. Seats are extremely comfortable. Fifth Wheel Prep made it extremely easy for my hitch installation. Amazing Sound System

The price was the best in the area and they didn't try to throw on add-ons. The process was seamless and I was pretty much in and out in a few hours. The truck was exactly as advertised.

Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me

This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

Happy with the ease of contracting business. The vehicle was brought to my house for a test drive. Within 24 hours the vehicle I was interested in was located and documents were on their way to me for signature. I also like that I will not need to visit the dealership to pick up the vehicle. It'll be delivered to me.

Great vehicle. Plenty room inside and back. Really nice interior exactly what I was looking for. All extras heated seats, Starring whell . Sun roof. Has everything. Ream happy with.

I was there for my 2019 Colorado truck service. Alex the front service guy was really helpful, easy to communicate with and really smooth transaction to the finish.

gladstone mitsubishi made the buying process easy and simple, helped me find the right vehicle and got me into the vehicle within the limitations that i set for myself. they weren't pushy and my salesman christian was very educated and helpful.
