Purchased a new 2025 Toyota RAV4 from Ken Ganley Toyota
Purchased a new 2025 Toyota RAV4 from Ken Ganley Toyota Akron. Our salesperson, Jesse Willig, made our experience buying a new car the most relaxing and no pressure sales that we have ever had. Jesse was up front and honest with us during the entire process. Jesse did everything he promised and we took delivery of our vehicle without hassles and took no time at all. Matt Middaugh, financing, was very nice and there was no pressuring us to finance through Ken Ganley Toyota Akron or buying additional products and services. Our tech guru, Lucas (sorry, didn?t remember his last name), was very friendly and was able to help get the technology setup on our cell phones. Both Lucas and Jesse helped explain other features of the car. Go check out Ken Ganley Toyota Akron for your next used or new vehicle, they will do right by you. Tony & Janet

Brad was our salesman.
Brad was our salesman. He was very accommodating and showed us the cars we were interested in. He wasn’t at all pushy, took time to explain all the workings of the car we chose. Answered all of our questions and very patient with us. Tim, the finance guy was also great. Didn’t try to sell us on every option offered. Definitely recommend this dealership if you are looking for a Toyota!
Bought the car CPO in summer 2021 with 38k miles.
Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

Gas and diesel terrain
I have owned 5 of the 2018-19 terrains. I have had the 1.5 gas, 2.0 gas and the 1.6 diesel. The power on the 2.0 is awesome. Mileage on the 1.5 is good. Mileage on the 1.6 diesel is great. I have 336,000 miles on my diesel. It has had lots of issues due to emissions and transmissions. Last week it got a new engine as well. The car is a great car but I would recommend the 1.5 gas for most people. The terrain is comfortable and makes a great work or travel vehicle. Size is easy to park with plenty of leg room.

My GMC Terrain saved my life.
Great savings on gas and mileage, very reliable and comfortable. Saved my life when I was in a big rig truck accident as driver side and front side bags deployed. I've become a GMC customer for life as I will be looking forward to buying another GMC SUV.

Dealing with the sales person was an excellent
Dealing with the sales person was an excellent experience! It so nice having a fellow VET helping me with the process. My son is so pleased with his new car! Now he has to pay me for it. Lol
We love this automobile.
This is a higher trim model with the bigger 4 cylinder engine (2.0 vs. 1.5) most of the options including Bose sound system. We love our pick and the only reason I gave 4 stars to comfort is the ride. Granted it rides nice, but you only get 5 stars from heavier sedans. Trucks and SUV's just aren't designed for that really smooth ride. Definitely would recommend the 2.0L engine if you tend to pass on a 2 lane road or need to pull out quick in traffic.

Over the past 15 years, we’ve bought several cars from
Over the past 15 years, we’ve bought several cars from Dave Somerville, and we’ve sent countless friends and family his way. The few times we went elsewhere ended up being really disappointing experiences. Dave is a true professional. He listens, guides you through the process, and genuinely wants you to drive away with a car that’s right for you—not just make a sale. If you’re in the market, I highly recommend stopping by to talk with him. Be honest about what you want (and don’t want). Dave will go to bat for you and make sure you have the best experience possible.

I bought an Alfa Romeo SUV recently from R21 Motorsports.
I bought an Alfa Romeo SUV recently from R21 Motorsports. After 4 days I began experiencing engine trouble. I also purchased an extended warranty with the car, a practice I would recommend for ANY car purchase NOWADAYS. The warranty broker Nick S. worked tirelessly with the dealer to work out a solution that worked for all parties involved. This was an unfortunate situation, but to Tad and the dealership's credit they stood behind the product they sold and worked out a solution that was fair for all parties involved. Based on my experience with a difficult situation that they stepped up on, I would recommend purchasing a vehicle from R21.
