2025 GMC Yukon review
A overall quite reliable car, I’ve owned this Yukon for a couple of months and it’s treating me well, it’s nice, it’s luxurious, with high resale. Yes it consumes a lot of gas, but besides that, best car I’ve owned.

El Dorado Chevrolet review
Honestly, best deal we've ever made with a dealership. We went in with a specific deal in mind, and it was actually accepted! Very little negotiation! These folks made the impossible happen!!!
2025 GMC Acadia review
I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

The team was respectful of my limited time. Very knowledgeable of my car and offered a very fair price for my trade in. Highly recommend.
2020 GMC Sierra 1500 review
Overall a great vehicle but I’m always concerned about potential DFM & 8L90 transmission problems. I had to replace four fuel injectors around 60,000 miles. I recently replaced a speed sensor in the transmission but this was at 110,000 miles. Others have not been so fortunate. This is not a vehicle built to be “hot rodded”. I strongly recommend 5,000 mile oil changes. Otherwise it’s absolutely the best vehicle I’ve ever owned. Hope to drive it to 250k or so.

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

2025 GMC Sierra 1500 review
Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

2025 GMC Canyon review
I purchased my Canyon after getting rid of my 2025 Rebel lemon. So far the truck has performed flawlessly. I'm 6'2 and the vehicle has been comfortable even after a 3000 mile road trip. It looks great, is easy to maneuver, and has plenty of comfort and safety features. The 4 cylinder turbo has adequate power but could use a little more in my opinion. I average just under 20 mpg in mixed driving conditions. The rear seat is a little cramped for adults but other than that I don't have any gripes.

2022 GMC HUMMER EV review
Currently, the Hummer EV is a decent electric vehicle option. However, as newer electric vehicles, especially the Cybertruck, are released to the market with longer range and cutting-edge features at a lower price point, the Hummer EV will fall behind. The Cybertruck is anticipated to enter mass production later this year, while GMC's production is slow, putting them at risk of falling behind competitors who may enter the market with newer and better offerings by the time GMC's product is ready for a refresh. Although GMC initially released a good retrofit product, their production delays are gradually eroding the Hummer's competitive advantage.
