I would never buy or consider buying a vehicle from this dealer. They do not stand behind what they say and I was so mistreated by the sales manager. I have never experienced such terrible customer service in my lifetime!! Not only did the sales manager yell at me when I did not agree with him and when I asked where my car was that I special ordered. He also forgot that I was they paying customer.
UPDATE/CONTINUED...They misled me on the vehicle I special ordered. It did not have the options that I specifically asked for. I specifically requested ambient lighting/heads up display/I paid $900 for navigation and it was not even navigation. When we built the vehicle, they said it was on the 2LT model and they said they ordered those for me when we built it together online. None of those options even come on the 2LT model. They are on the 3LT model! The salesman had no idea what he was even ordering! I went to another dealer to get the exact and right vehicle! AMAZING HOW ANOTHER DEALER CAN GET IT EXACTLY RIGHT!! By the way, owners response is inaccurate...the GM family discount was approximately $3200 savings for me. They were trying to pad my discount for almost $1000. It's my discount and I was not even getting the full benefit. Talk about trying to sham a customer! The most horrible customer service and buying experience I have ever had!
