Heritage GMC Buick

I made my appointment 2 weeks before through the GMC app, on the day of my appointment I arrived and the man who attended me first told me that he was not in the system, that I should come back later, that I on the day of my appointment I arrived and the man who attended me first told me that he was not in the system, that I should come back later, that I should make an appointment by call because the app doesn't send it to them, then Marcus arrived and he wanted to take my truck for the scheduled service, it's not my fault that the app doesn't work, the dealer and all of GMC promote it but it can't be used because it doesn't work? Apart from that, after they rotated the tires, my truck is vibrating when I drive at 70 m/h, now I don't know how to make the appointment More

He is an experienced professional, informative, pleasant, and responsive - all of the things you want in a good salesman. (We first met in 2014 and have purchased 3 new vehicles from him to date.) This visit was no exception. We bought a beautiful 2024 GMC Sierra 2500 HD SLT and couldn't be happier with the truck, the deal, and the trade-in allowance on our 2015 Sierra (which, incidentally, we bought from him). Thanks go to Mario, and also to Daylan, the finance director, who got us in and out quickly! You guys are the best! More
