My wife and I purchased a used 2015 Buick Enclave from
My wife and I purchased a used 2015 Buick Enclave from Mike Maroone Cadillac GMC. We live in western Nebraska and saw the vehicle for sale on cars.com. I visited the Mike Maroone Cadillac GMC website directly and found the vehicle on there. There was a wide array of documents related to the vehicle right on the website. I was impressed with the transparency of the information that was offered. I was even able to access the vehicle’s Carfax right on the website. The vehicle was a one owner with a crystal-clear service record that had every single oil change, preventative service, and recall completed on schedule. Negotiations began though a series of phone calls and text messages. Our salesperson, Braden, was very nice and professional, but most of my contact during negotiations was with two of the sales managers, Andrew and Anthony. Both were equally transparent, straight-forward, and most of all very fair to negotiate with. Using only a total loss settlement we received from an accident, we had a limited budget to work with and they really knocked it out of the park! We drove out from Nebraska on Memorial Day weekend to test drive the Enclave and put the finishing touches on the negotiations. Everything went off without a hitch! Even though we paid for the vehicle in full that day, we still had to go through the finance office for all the sale documentation. Eric was fast and friendly, and we were on the road back to Nebraska by mid-day. Unfortunately, on the way home, we discovered an issue with the Enclave’s transmission. We were crushed and started panicking as to what to do. Used cars are sold as is, and we knew that going into the deal. We knew we couldn’t return the Enclave, so we drove it the rest of the way home. Brayden called us on Sunday to ask how we were liking the Enclave. I did not answer and did not return her call until Tuesday morning since it was Memorial Day weekend. I left a message for her explaining the transmission issue and that we were aware that it was sold as is. I then took the Enclave to a transmission shop and had it diagnosed. The Enclave needed a new transmission to the tune of $5,800, plus tax. I received a phone call from the sales manager Anthony and within 5 minutes he offered to pay for HALF of cost to replace the transmission! I sent him a copy of the invoice from the transmission shop, and I had a check in my hand by the end of the week! When I thanked Anthony, he told me, “Doing the right thing isn’t always easy, but we are always going to do the right thing”. Mike Maroone Cadillac GMC earned a life-long customer here and I will make that drive to buy from them again anytime! Thank you, Braden, Andrew, Eric and most of all, Anthony! You are all a class act!
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

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.

Abe with Truck Kings found me my dream truck and brought it to me with everything customized to my taste-even down to the interior floor mats. He had all the connections to get me financed and the entire process was quick and easy. no detail was overlooked from tires to windshield. I would highly recommend if you need a new ride to stop by see what he has to offer.

Promasters
I have bought two promasters from these guys in a bout six months time. As a business owner I don't have much free time was able to get in touch with Jeff Hale and put the ball in his court. It was the easiest purchase iv made I spent maybe 1 hour each buy at the dealership just to shake hands sign pick up and out the door ! No hassle got what I wanted for the price I wanted even a little cheeper. Will keep my business here!
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.

Over-priced car.
Over-priced car. Sales person very persistent. Very far away from my residence. Not sure if I am interested or not. Have owned three other Mustangs already.
Great Truck !
First , I bought gas 6.0 , the diesels are great if you have serious towing needs. You just need to realize no matter how well you maintain a diesel it will at some point have an expensive repair. I've had my truck about 12 years. Regular maintenance , a few batteries , couple sets of tires and a MAF sensor. I tow a couple different trailers and the heaviest is less than 10k loaded. Towing , zero issues , no band aids , no overloads , no equalizing hitch , no sway control. Simply not needed. Drives amazing, stops great, Roughly 10 to 12 MPG towing. Unloaded driving at 60 / 65 on cruise solid 15 to 16 MPG. Yes , it won't pul the hills like a diesel but thats a small price to pay for an absolutely amazing truck. I want a new truck in the worst way but just can't part with this truck. A very good truck if you find a clean well maintained one.

Greg Wolaver was a great help in regards to my long distance purchase of a used Jeep Commander. He was up front during the whole process and greatly assisted in the shipping process. I haven’t gotten my vehicle yet but if it’s half as good as he stated it will be a great purchase.
Overall Great Truck
I bought mine in 2017, 2nd owner. It had 36,000 miles on it when I bought it, getting ready to turn a 100,000 miles, and the only thing I've had to do to it, is replace the Def heater, other than that, it's been a great truck. 👍
