2020 GMC Sierra 3500 review
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.

Jim Schmidt Chevrolet of Delphos review
Zach was very helpful and answered every question I had and I had many. I purchased the Toyota Tundra in Ohio and I live in South Carolina. With that said the sale was seamless and the dealer offered to bring the vehicle to an airport closer to me. This saved me at least 2 1/2 hours in travel time to get back home. Everyone was very friendly and helpful with this purchase. Highly appreciated and recommend but Zach and the dealership. Thanks again
2026 GMC Sierra 3500 review
Overall pretty good, however it is undocumented if you turn off or adjust some of the safety setting it will cause light on dash to come on and make you think issue with system (ex collision if you change from default of alert and brake to alert only). I think this is an issue and should not light dash light to indicate an issue with the system because of alert settings.

Thanks to Aubrey and the rest of the staff at Lehigh Valley Hyundai. Theywere just amazing to work with. No pressure tactics, and we ended up getting exactly what we wanted for less than we expected. We'll definitely be buying a car here again someday.
2022 GMC Sierra 3500 review
I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

2024 GMC Sierra 3500 review
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.

Highline Motor Cars review
We recently purchased a 2003 Ford Thunderbird from Highline Motor Cars. Ali was our salesperson and he was very helpful. After looking around for this particular model, we found exactly what we were looking for. Ali gave us a good deal and was upfront regarding some routine maintenance the car would need. The car itself was in fabulous condition for it's age! We now have our "retirement" car to take weekend rides! Thank you to Ali and the crew for even offering us lunch! I was waiting for the weather to break (finally) to take a nice drive down the shore and we are in love! Thank you again Highline! We recommend your dealership for a good deal and honesty!
2021 GMC Sierra 3500 review
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.
