Amazing purchase experience
I found a truck on cars.Com and did the normal thing sending a request to ensure it was available. Mel reached out to me via an email message and mentioned that he would contact me later in the day. He called me later that afternoon. After that very calm conversation, he gave me very solid reassurances that a different Ford dealership had lied to me about some things.. I already had pre approved financing at my credit union, so this was a fairly straight forward process. Mel made this process so easy. I'm not a youngster with no experience. I know how this process should go. This was not my first truck buying experience. Mel is a true professional and an asset to not only his profession, but to Five Star Ford. He's a rare find in this industry. This was the easiest and most positive truck buying experience in my life! Thank you to Mr. Melvin Seibel!
Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Wonderful experience!
Wonderful experience! Our salesman Ricardo Magana was knowledgeable and easy to work with. He made sure everything was working on our car before we left the dealership. It’s our daughter’s first car and we feel she has a good reliable vehicle.

So I pretty much been dealing with one Gentleman name Craig and have been an easy person to speak with and very knowledgeable about things I ask of him.
141,000 SLT Still Going Strong
SLT with most options. Purchased at 127k. Currently have 141k after 17 months of ownership. The tranny that came with it was not original. I have had to replace ball joints, a/c condenser, brakes, wheels, radiator, a battery and a starter. Can't complain at this mileage. This is one of the quietest vehicles I have owned (that includes Audi A8's) and it's shod with Cooper Discover AT3's that chomp through snow like my Toro snow thrower. I also replaced the stock halogen bulbs with LED's and what a difference! The interior is comfortable, and I did replace the drivers seat bottom cushion. The nav system sucks, it's not very intuitive and it isn't very good at mapping the best route. Besides, I use my sedan for long trips. Phone integration is a breeze. Radio surprisingly decent. Everything works as it should. It's easy to pop the kayaks in the bed and the ebikes on a carrier and head out for the weekend. When moving stuff, I have the 80" bed so I can fit loads of stuff under the hard tonneau cover. The interior still has NO squeaks or rattles. Amazing. The heated seats are slow to heat, and the heated wheel is slow to warm up. But this thing is such a beast in the snow and rain I don't want to drive anything else! All in all a very reliable, well-built, and for the genre a good-looking vehicle. People tell me all the time what a nice looking truck I have. It's stock. Thanks, GMC.

My family has purchased 5 cars with the help of Auto
My family has purchased 5 cars with the help of Auto Locators over the past 15 years. They always take the time to truly listen to your wants and needs and we have never felt pressured at all. They have always gone over the top to take care of us ( I even referred my boss who purchased a car with them). We wouldn’t hesitate for a moment to use them again or refer them. They always take care of there customers.
Great Truck
The Truck has been great since I got it. Great driving and comfortable interior. The truck will be used for our trips to Nebraska and Indiana.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.
