Awesome!
No pressure to sell. Byron was of tremendous help, knowledgeable, and loved to share his fathers great history in service to his country. He even sent me home with great reading material on him. Prestige went to long lengths to find the right car (my wife will ONLY drive a stick, drives me crazy!). No manuals on the lot, so they sought the countryside to get just the right one. I highly recommend prestige to anyone.
Very beautiful truck
This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

I recently traded in my 2016 Jeep and leased a 2025
I recently traded in my 2016 Jeep and leased a 2025 Tacoma. The sales person I dealt with, Ron Smith truly went above and beyond ensuring I got a more than fair trade in value for my Jeep and found me a great new vehicle at a great price. I probably was not the easiest customer to satisfy but Ron stuck with me and was extremely patient and courteous. Ron maintained a great balance between being very helpful while NOT being a pushy salesman. If you are planning on looking for a new car I highly recommend Corwin Toyota and suggest you ask for and wait for if necessary Ron Smith. Thanks again Ron.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

2020 GMC 2500 AT4
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.

Great expierence
Abe listened to the type of vehicle I was looking for. He was able to find me a very clean truck that met all of my expectations and more. He also made the financing very easy to understand and complete. Will purchase from again.
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Five Star Service!
I drove right in, the Service Associate that greeted me was very polite and explained exactly what was going to be done, as I waited for my vehicle he came to check on me and asked if I had any other questions or concerns, it was a great experience and I will certainly be returning to Transwest GMC for all my service needs
Best Truck I ever owned!

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.
Most convenient options on any vehicle I've owned.
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.

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.
This is your Truck
When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

How easy it is to work with Johnson Auto Plaza.
Purchasing my new 2022 GMC Sierra was easy as buying something through the drive-thru. The salesperson, Chris Maneotis was awesome. He explained how my trade-in would go towards the purchase of the new truck and went over the financing and options. I would highly recommend anyone to work with Johnson Auto Plaza.
So far have loved my 2020 2500 HD 4x4 diesel
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.

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.
