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!

I dealt personally w Manny Rodriguez. He was intelligent, knowledgeable, honest and transparent. I applaud MM Chevy for hiring such an inspiring young man. Would go back again in a heartbeat!! I purchased a nice Silverado due to Mannys professionalism! Phil Bravo

Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

Looked for a low mileage Acura TLX or TSX for six months and I found this car near me. It was nicely detailed and looked well cared for from the posting on Cars dot com. The sales rep called me very soon after my initial query. The entire buying process took an effortless one hour and I was on my way with the beauty,

Joey was great service manager...car service correct and prompt...very positive experience. Car was returned clean and with a full service report. Highly recommend dealership.

Rafael H was very attentive to what we were looking for in a clean used diesel p up . His assistance in our purchase with our purchase was very good . professional, not pushy Gerald & Kay Schreiber

Austen is knowledgeable, efficient and friendly. I love that the tech sends you a video of your vehicle and what he?s working on. And the best of all is that they got me out in a timely manner

Yamile was knowledgeable, professional, empathetic and a terrific asset for you. She is a keeper!!! I could not be more pleased with the service she provided.

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.

Always a pleasure to get my truck serviced at Mike maroone Chevrolet, gmc, Longmont. Joe was my service advisor and got my truck in and serviced a lot faster then i expected. Service was an awesome. Thank yous

Worked with Cosmin on a used Porsche Cayenne. Very friendly and professional salesman with a no-xx attitude. Didn't leave me waiting around excessively during price negotiation, and was willing to work with me to find a deal I was happy with. Finance was super quick and low-pressure, I didn't feel like I was being lambasted with upsells that I made clear I didn't want. Good stuff, Austin. Very respectful and professional staff, and I would definitely recommend doing business with these folks. Keep up the good work.

Friendly and knowledgeable staff. Thank you for your help and we love our new car!
