Great dealership! All the Staff are very inviting but not right away pushing a sale. Other dealerships in town can learn A LOT from all the staff of Mini of Tucson! Our salesman who has been with the company about 3 months is so knowledgeable about the Mini it is very impressive! Javier when we get another down the road we are looking for you at Mini of Tucson! Thank you all for the great experience to your home away from home!
Comfortable
Bought this truck used,I love the comfort. I used to have a ranger.I can fit my plywood in the bed and close it.It is a long bed.My 12 foot jon boat fits good,.better than the ranger and more comfortable

We really liked our vehicle!
My husband and I are from Granite Falls, MN. Duluth Motorsports has a 1976 MG Midget for sale. We worked with Sean. He was a complete gem! We drove 245 miles (one way trip). We got the car home and couldn't be happier! Thank you to Sean and Brandon!
So far so good
The truck runs great. preformed exactly how I need it to. Has everything I wanted except wireless/Bluetooth an back up camera. But all that can be installed later.

Ford
I recently bought a Ford from this place and I'm super happy with it. A lot of these cars have high mileage but are inspected for at least 2-3 years so i'm sure if theirs any issue you'll have time to fix it. However they can be a bit pricey and overcharge so check kelly blue book to make sure your getting a good deal.
Good truck if you do the right things
The best thing about this truck is the fuel economy. Bought brand new in 2012 and when the truck hit 35000KM the fuel economy improved. I had heard about that before but didn't believe it. Beware, these trucks are known for transmission shutter and shifting problems like every GM product ever. Do not flush the transmission ever. Pull the pan and replace the oil three times every 40 of 50 KM. It costs a bit but the tranny will shift much better and last. The door handles are garbage. They cost 25 bucks on Amazon. Changed two now. Changed washer fluid sensor. Front breaks and rotors are cheap. Replace with high end aftermarket when they go...and they will. Over 200 Km on this vehicle now. Motor is strong and the truck is still holding up well. I would give it a 5 if GM would get their transmission issues fixed one day. A little higher quality front end parts would put them over the top. Good ride, roomy and comfortable.

Tamal was the best! Very down to earth yet direct and honest throughout the whole process! During Test drive he sat in the back so my partner and I could feel things out for a realistic perspective. Would recommend this dealership to anyone who wants a great experience! Straight forward, fantastic pricing, great dealership!

As a first time buyer and financing I was apprehensive
As a first time buyer and financing I was apprehensive about right step to take in a field so vast. I wanted honesty, guidance, clarity and a vehicle that will meet my needs. At Car Corner I found Rick and he kindly walked me through every step explaining clearly all paperwork and car information and because my time constraints he did it all in a day and out the door I went with my new to me beautiful car, completely inform, happy and with at the bottom line is most important! Peace of mind.

Ms. Gale
Absolutely the best experience I have ever had buying a car! Dave was patient, actively listened to me describe my situation, and responded by making sure he completely understood my what had been said to him. He was honest in his response to being able to work with my challenging credit situation. He made no promises to get me to come to the location. He never once made me feel bad about my challenging credit situation. Life happens to everyone, this gentleman worked hard on my behalf so that I could have a chance at regaining my creditworthiness. He only asked that I have all documents with me when I arrived so that he could efficiently begin to work on my situation. He was pleasant, professional and most of all HONEST ….. Even when my credit was great I have never experienced the level of compassion and professionalism as I did with Dave. It did not take hours of frustrating time sitting, feeling belittled and being told one thing and then another to only find you have been taken advantage of in the end. I do believe this was by far the best car buying experience I will ever experience! I will definitely be going back to see Dave when I have to purchase another car. I highly recommend him to family and friends as well. Definitely do place a call to or go see Dave, he will provide service with integrity and professionalism.

Yearend 2025, I bought a 2019 F250 from Jeff Smith Ford
Yearend 2025, I bought a 2019 F250 from Jeff Smith Ford in Byron GA. They are a no-nonsense dealer that delivers quality vehicles in a professional manner. If you're in the market for a new or used vehicle, I highly recommend them. Ask for Marvin Jones in sales and James Gilstrap in service and you're sure to have a great customer experience in both sales and support. Thank you, Gents, Mark M

I had an excellent experience with Nick and I can’t
I had an excellent experience with Nick and I can’t recommend Transwest enough. From start to finish, they were all professional, knowledgeable, and transparent. My car has been having some issues and when I took it in for an oil change Nick quickly diagnosed the issue, explaining everything in a way I could understand. Nick went above and beyond, even offering helpful maintenance tips to keep things running smoothly. If you’re looking for a reliable, skilled shop with great service Transwest is the one to go to!
