I bought a new Camry Hybrid from Mountain States and had
I bought a new Camry Hybrid from Mountain States and had it shipped to another state. My sales representative, Paula, was awesome throughout, and Ryan, the sales manager, was as well. I naturally had several questions before and after given the out-of-state purchase, and both Paula and Ryan were super responsive and generous with their time in making sure everything worked out with the purchase. Strongly recommend Mountain States. Ask for Paula!
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great Place to buy a car
I was in need of a new car . The one i had was bought in 2005 but the year of the car is 2001. I wanted something a bit newer and affordable. I didn't catch the guy's name since my dad was the one who dealt with him first. No pressure at all. He was very helpful. I test drove the car and loved how it drove along with it's a big upgrade to what i had. So decided to buy it. I bought a 2012 Infiniti G25x, leather seats, AWD. front seat heaters, sun roof, backup camera, defrost on the side mirrors and it's a V6. I love it. I highly recommend buying a car here.
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.

A dealer like no other!
I usually dont write reviews but my experience with Truck Kings deserves one. Erase any idea you may have of a used car dealer and its inventory and replace it with satisfaction, enjoyment, zero frustration and a buying experience like no other. I had found Truck Kings from an ad online for a vehicle and went there to take a look at it. As it turns out they had 3 trucks that I was interested in. All 3 trucks were beautiful, straight and clean. Abe the owner of Truck Kings and I started discussing buying and trade options. Abe displayed a true knowledge of what he had to sell and was forward and honest about the strengths and weaknesses of each vehicle that we were in discussion about. His knowledge and honesty help me in making the decision as to which vehicle I would ultimatly purchase. During our discussion my trade in vehicle was in play and Abe offered me a very fair price on it. Finalizing our transaction I was left with a feeling like I had been treated well on the sell of my old truck and the purchase of my new truck. There were a few minor items on my new truck that needed to be fixed or replaced and Abe said he would take care of them, he did so promptly only a few days after I had taken delivery of my truck. Abe is a man of his word, his word is his bond and he is a gentelman. If you are in the market for a truck, take time to visit Truck Kings-Abe does some amazing customizing work, I get comments on my truck almost everytime I drive it. He keeps clean good looking inventory and I will definitley be back when it is time for another truck. Abe runs a clean, straigtforward and honest shop. He fascilitates a no pressure enviorment and can help arrange several different financing institutions to help you in getting the best deal avaliable.
