2020 GMC Sierra 2500 review
I have owned my truck for a month and two weeks. Two weeks after owning it my power steering went out for about 25 miles then was OK again. Last week the check engine light went on and after about 25 miles it turned off and it was OK a week ago I entered my truck to start off for the day and everything was dead absolutely had no sign of life. The dealership has now had it for exactly a week and they cannot figure out what’s going on. They say they’re having problems receiving communicating. I sure hope I will continue to love my truck. It drives like a dream and pulls like an ox.

Huntley Ford review
We really appreciated how dedicated the staff at Huntley Ford were. We spoke on the phone and visited to check out a few vehicles with Daniel. He was very patient and wonderful to work with. Although we didn't purchase a car during our visit, we would recommend that anyone visits the dealer for a great experience.
2020 GMC Sierra 2500 review
Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

CarMax HuntsvilleReviews
CarMax Huntsville review
After checking all around for a lightly used Honda or Toyota minivan, I settled on CarMax since they had the ability to transfer several possible cars from nearby stores. I requested a transfer from Birmingham and it arrived earlier than promised. I test drove it, waited a week to make a final decision and made the purchase. The whole transaction was done professionally and without any extra sales pressure or tactics. This is the 2nd car in the last 6 years I've bought from CarMax and I'd certainly shop them again.

Motor Cars of ChicagoReviews
Motor Cars of Chicago review
I recently purchased A 2018 Alpina B7 from Ray at Motor Cars Of Chicago. When I purchased the car I made it clear to Ray that I was going to be in need of the title in ASAP fashion – Ray said I’d have the title within two weeks and boy did I just like he said he fulfilled the promise he made no questions asked. Also on the way home after taking delivery, I had a very minor problem that turned out to be a bad battery. Ray was unaware of when we took delivery of the car – Ray didn’t hesitate he reimbursed me for the batteries I had to have installed at the BMW dealer by the BMW dealer. He said the car was flawless and he stood behind that statement. Ray is very straightforward and no xx perhaps not full of warm fuzzies for everyone but a great way to do business, especially in the luxury and highline car business. I find Ray to be honorable direct and stand up and we’ll do business with him again if I had any reservations about doing business with them before this transaction, they are all completely gone and yours should be too. Thank you, Ray for a great transaction and a great automobile.
2020 GMC Sierra 2500 review
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.
