Highly recommending to dealership, no sale pressure, outstanding, exceptional customer service and good pricing. I definitely will come back!
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.

Good Experience n purchase!
I had an incredible good experience with these fine folks. Orlando n Shawntal were amazing and made the purchase of my SUV go so smoothly. Very friendly and kind staff. I am so pleased with my purchase!
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.

It’s easy to smile and shake hands!
It’s easy to smile and shake hands! Walid & Tanner absolutely went above and beyond. When the car itself didn’t cooperate with the sale they both went great distance to make it right. They were patient. They listened and they made it right. Thank you
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 very disappointed customer still love Mullinax
I have no problems with the dealership. My mother purchased a Ford Mustang in 2006. This have been the only place it’s ever been for services. The car had a few problems of shutting off on its own twice two consecutive times when it had few hundred miles on it. Had an alternator replaced two years after that. While under warranty paid for it. Fast forward years later by 2013 2016 I had some belts replaced and they were replaced in the wrong manner they were crossed over my water pump hose as I drove it home I saw steam so I took it back up to Mullinax to tell them what the problem was. They said all kinds of fluids damaged the entire engine by spewing out. So it had to be replaced and it would no problem replacing it because it wasn’t my fault a mechanic negligence. So I wasn’t offered a newer engine for my troubles I was offered a used one don’t no how used it was. Probably About 2years from that the heads went out on the used engine. I proceeded to ask why should I pay almost 2,000 for something that shouldn’t be my fault an the engine I have not so old well atleast I thought and I was told that’s the only time they can honor that it will be on them. Of course I feel it should be an I shouldn’t have any type of issues for another 100,000 miles for my car to be an 07 I have about 109,000 miles on it I drive it to keep everything basically flowing and not rust or anything an I do understand somethings will go bad. I’m a dear customer and I tell Plenty of people to shop there if they have or not i put Mullinax up highly. I financially would love to get a truck from Mullinax one day. I have a friend a salesman’s there. Now I have another concern I took my car to be check out at Mullinax a a little time back months ago ,cause something causing my battery to go dead an my wiper motor went out so I purchased a wiper motor an was about to put it in myself but I don’t want to do that if my battery going dead for some odd reason. If I have a Ford an now my car is in the category of being a used car I was told from the service tech the mechanic couldn’t find out the issue. This suppose to be Ford dealing with a Ford vehicle. No recommendation or anything. So I’m stuck on finding a 2nd 3rd party. It shouldn’t be that way.

Mustang Convertible , EASY remote sale
Taylor Ford of Manteno set the bar across the board for a perfect remote experience. From the moment I reached out with a brief inquiry on their website and their sales people were not only responsive, but extremely kind. They assisted me with walking me through the entire process. It is very hard to buy a car sight unseen but the videos and information made it easy. They even went out of their way to make sure I was satisfied even AFTER my purchase . Driving it few days later. Absolutely LOVE my red convertible mustang. Good Experience guys, 5 Stars All Around+++++ Thanks Abbie and my Sales guy!

Don't buy a used car
Purchased a used car 2019,sonata. Under the impression that as a used car with a inspection done. That 3 months after purchase I wouldn't be told I need repairs in the future. Brakes,rotors,cv replacement. Felt like it wasn't worth the dealerships time to do it.

I was treated with the utmost respect .I was greeted immediately by Adrian. He was very knowledgeable and curteous. I was in constant communication with him and Gary. This was the most comfortable time I have ever had in a dealership. I would recommend anyone to come to Orland Toyota and get a fair deal .

The Paws & Pumpkins event at Winchester Mitsubishi was
The Paws & Pumpkins event at Winchester Mitsubishi was one of the best community events I’ve attended. They truly went above and beyond—free pet adoptions, adoption kits, toys and treats for the animals, candy and activities for the kids, prizes, music, and a warm, welcoming atmosphere. What stood out most was how genuine the staff was. It didn’t feel like a dealership event, it felt like a community celebration with a purpose. They showed they care about people and pets, not just sales. If they host another event like this, I’ll definitely be there.

Very helpful and professional
Was looking for a possible vehicle and had a very good experience with Bill Morrisey at the dealership. Walked me through a number of different cars and due to my circumstances changing I decided not to buy a car at this time. But I would feel very comfortable using Harbro in the future.

The fact I purchased the second car in 2 months says everything about the amazing experience with the Jack Daniels dealership. My purchases wouldn't be possible without Christian Tatar's professionalism, knowledge, and honesty. The rest of the team was amazing, special thank you!! for a second time to Scott finance manager and Doug Sales manager. I would highly recommend this team and would purchase from them again!.
