I enjoyed working with Elijah and the rest of the sales team. They provided the information I requested and accepted my decision to purchase the car, but didn't press when I said I wasn't interested in any of the add-ons.

Great Experience
We bought an Audi Q7 from Marcella. She was friendly and upfront. The dreaded finance office even was pleasant. Car prices are what they are. I’d buy another here. Was disappointed with the 1/4 tank of gas lol I left more in my trade. And no inspection sticker. But overall great and those 2 things would not deter me.
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!

Jesus, who handles the internet request, was prompt to respond to my inquiry, and was waiting for me when I arrived at the dealership. Answered all my questions, very professional, helpful and yet friendly.
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.

Overall great dealership. Love Staff in Service dept and my personal sales rep, Richard ? looking forward to my new 2026 Equinox!!!! Yes Yes okay okay
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've worked with Tony before & he is very knowledgeable & knows just what we like.
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.

I had a great experience with the process of returning my leased vehicle and selecting a new one. Having owned and leased several Chevys over the years, this was actually my first time at Tim Lally, so I wasn’t sure what to expect. Justice was my salesman. He was courteous and helped me find the right vehicle. The management team were equally impressive and able to negotiate a price point that fit my budget without resorting to high pressure sales tactics. Not sure why I waited so long to check this dealership out, but I will definitely be a repeat customer! PS - love my new 2026 Trailblazer.

Purchased my 2025 Bronco today and the process couldn’t have been more easy. Dylan was our sales rep. He was absolutely amazing from beginning to end. The manager came over to introduce himself and was very personable. The gentleman who did our financing was the absolute BEST! I have never had a car buying experience as easy and as fun as I did with Kunes. I rang the bell and they added a big red bow at my request. We were treated like family. I was overjoyed. Didn’t feel like a car buying experience felt more like a gathering of family and friends. Thank you Kunes

My product specialist,, Carlos Isava, made the purchase process comfortable & smooth. He was professional, knowledgeable, and is very personable. Alex in finance also, allowed me to feel comfortable in that phase. He, too was friendly & professional. Not once did I feel pressured by either gentlemen. I would definitely recommend Ed Morse Sawgrass. My experience was great!

I have bought my last few Subarus from this dealership
I have bought my last few Subarus from this dealership even though it is further from my home than at least 3 other Subaru dealers. They always seem willing to make me a nice deal on a new car, and they go above and beyond making the the process fast and convenient. Further, the sales representative with whom I worked, Reid Stanley, was accommodating, calm, not pushy, helpful and informative. Really everything one would wish for in a sales associate.
