Lauren Hyatt contacted me right away the next morning to arrange a test drive for the bmw 7 series i was interested in. she assured me we could do everything remotely.
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!

Parker is awesome. Very kind and knowledgeable. Got me in and out as fast as he could.
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.

Living my life like it's Golden!...
First let me say that this review is coming straight from my Heart, and I am so Grateful that I discovered the Right Place Auto Sales. First of all the Customer Service was delightful, the Sales People Alphonso and Tyrika were not only very friendly and Professional, but they were also super helpful and sincere about helping me get into the Right Vehicle for my needs. Secondly they worked to find me a Lender that would fit my Financial needs. They asked how much I could afford and from there they worked their Magic in getting me the Right Car and the right Creditor for my Budget. I have been driving my new car for about a Month now, and it feels like it is a very dependable vehicle. I feel blessed and the Right Place Auto Sales...is definitely the Right Place to buy a Car. They got me on the Road and now I'm Living my life like it's Golden! Vroooooom!
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.

We were happy with the shopping experience to obtain a 2020 Subaru. Jason Saravia was very helpful and easy to work with, and the sales James and Will were also great.
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.

Im in the process of buying a car from here. The prices are alright, and hopefully it’s a good experience as it has been so far. Will update if this changed
Best choice
I love my car thus far. It included every feature plus a couple extras that I was looking for. Of all the cars I’d driven my Terrain Denali was the best choice for me.
