I would not recommend GMTV to anyone.
I had an experience trying to use their service to sell my Ram 2500. I filled out the application to get a quote and wasn’t particularly thrilled with their offer. I went to a local dealer who offered significantly more money for my truck and completed the deal there before letting GMTV know that I was no longer interested in doing business.
After that point, I received multiple threats primarily via text message that I would have to pay a fee for not taking their deal, criticizing me for not taking their deal, questioning my character, my word, etc. I screenshot all of the messages as I never did accept their offer or sign any contract and they tried forcing me into paying them just for requesting an offer. I never felt comfortable accepting their deal and they did not like hearing that, then the true colors of the company started to show.
Be very careful before considering any business with that company. You will likely do better at a local dealer and won’t have to deal with strangers treating you with utmost disrespect.
