The entire process was done virtually from Denver, CO, and effortless. Mark was willing to go above and beyond -- meeting my fiance and I in Grand Junction, CO, for the exchange. Due to severe weather conditions, he waited for our arrival for over 2-hours, and was notably jubilant and prepared with paperwork. The transaction took less than 20-minutes and the vehicle was in excellent condition. In fact, it was better in person and truly exceeded our expectations! We drove it back home for 5.5-hours and had no issues. It was definitely the test drive of a lifetime and gave me pure safety assurance. I highly recommend both Blue Diamond GM and Mark Marasco to anyone and everyone in the market for a vehicle. You'll have nothing short of a smooth, fun and memorable experience. He is flexible to meet any demanding situation. We will be back! Aleece and Kevin Tessin  More

Found a GMC 1500 on their website called and made a down payment for when it arrived worked out numbers. The truck came in and we drove 4 hours to pick up and finalize the sale of course they added on thing payment for when it arrived worked out numbers. The truck came in and we drove 4 hours to pick up and finalize the sale of course they added on things without our knowledge. Like a protective coating to the truck adding on 1200.00. Then they wouldn’t honor there $200 coupon off a new vehicle as given on there website. Just another typical dealership. More

I had poor experience with the service department no one had touch my car but this dealership. I also bought my car at this dealership got a flat on the front driver side when I changed the tire I found one had touch my car but this dealership. I also bought my car at this dealership got a flat on the front driver side when I changed the tire I found one of the lugs had been stripped out. It had to have happen at this dealership and they refused to fix it said it was normal wear and I would have to pay for it the car only had 20,000 miles on it and like I said no one had touch or rotated the tires but this dealer. So it had to happen there. I also took the car in to get the rear window washer fixed couldn’t find the problem said I would have to bring it back and leave the car I was so upset about them not standing behind there poor work with the lug. That I took the car to a different dealer they said it would cost 250.00 to replace the bad lug and they had the window washer fixed in about 2 minutes it was a plugged. I will never take anything to this dealer again very unhappy with them they will not stand behind there work and it will cost you. More
