1 Star – Disappointing experience after reaching an agreed price and attempting to complete the purchase I am writing this review to share my experience with Mark Christopher Auto Center regarding a agreed price and attempting to complete the purchase I am writing this review to share my experience with Mark Christopher Auto Center regarding a 2015 GMC Canyon SLT 4WD Crew Cab: I live about two hours away and made it clear from my first communication that I needed the true out-the-door (OTD) price before making the drive. The dealership provided a breakdown showing the vehicle price, DMV fees, documentation fee, taxes, and no additional add-ons. The original OTD price provided was approximately $27,026. After discussions, I made an offer of $25,000 OTD, explaining that while the truck had low miles, it was still a 10+ year old vehicle. I later increased my offer to $25,500 OTD. Mario Sanchez contacted me and stated he spoke with management. His exact words were: "And You Win" Based on that communication, I believed my offer had been approved and we were moving forward. I was ready to purchase and was not asking for anything else. I immediately left work early and went to my credit union. I provided proof of pre-approval and explained that I wanted to use my own financing. The only thing needed was a proper purchase order so my credit union could issue the check. Greg Hess agreed to provide the purchase order. The PDF sent to my credit union and me contained blank pages with a vertical black line on the side. My banker reviewed it and confirmed the document was unusable. I immediately notified the dealership and requested a proper signed purchase order. The next morning, after being asked if my credit union received the paperwork, I explained we only received blank pages. I was told it would be resent. Shortly afterward, I received this message: "I just checked looks like that truck sold last night." I was then offered a different vehicle. The disappointing part is that I had: Received confirmation that management approved my $25,500 OTD offer Left work early Gone to my bank Provided financing approval Worked with both my credit union and the dealership to receive the proper paperwork After being told the Canyon had sold, I checked the listing and it was still showing available. I also had another person submit an availability request and they received 2 responses indicating the vehicle was available. I was told the dealership system would update when third-party sites refreshed. I understand vehicles sell and that a purchase is not final until paperwork is signed. My issue is the communication and process. I was actively trying to complete the purchase, but the paperwork needed from the dealership was not properly sent and there communication stopped until the morning, and shortly afterward I was told the vehicle was sold. This review is based on my experience and the written communication I received from the dealership. More

I was thrilled to find the Chevy Tahoe LS I wanted at Mark Christopher. Jose made the test drive easy and Gregg hustled to speed up a required update after we explained we were in a hurry — I had a sick Mark Christopher.

Larry handled finance efficiently, and everything was completed (including detailing and a full tank) in under a few hours. I really appreciated the fast, considerate service from Jose and Gregg. Highly recommend. More
