I purchased a 2014 Mercedes GL 550 from here. I saw an advertisement of it from this dealership and it fits what I'm looking for, dark paint, dark interior, and 7 seats... and it was an ok price for the amount of mileage on it. I work long hours and live about 90 mins from this dealership... So I didn't have a lot of time to go back and forth for a car purchase. I showed up to the dealership about 7:30pm on 6/25/19 to inquire about the vehicle. It was available. I drove it around the parking lot and was ok with just buying this and move on with my life. A guy named Sanjay helped me out... nice as could be. We did the paperwork for my purchase and trade in. The dealership even stayed open a lil later past their closing time to finish up my paperwork. I'm satisfied with the purchase..... but here's where they earned their ONE star... the next day, I discovered some minor flaws... I was ok with them, because it is a preowned vehicle after all. Sanjay sent me an email, thanking me for the purchase... So I responded with the list of problems with the vehicle: there was a small crack in the tail light housing unit, the bulb was also burned out, the back passenger side door doesn't operate, 3rd row seats are missing their headrest units, driver's seat soon became nonadjustable in certain ways, and after about a few days of driving, the brake pads needed to be changed... I didn't hear from Sanjay after a few days... So I called and left a voice mail. About a week later, after no response, I called the dealership and briefly chat with a girl who answered the phone... she said she'll let the sales manager know and that he will either call me later that day or the first thing tomorrow morning.... of course that didn't happen. It was a busy time for me... so I didn't press it. I also purchased an extended warranty... So I guess I'll just use that since the month of waiting is over and it's now in effect. .... Overall... the buying experience is good... but I don't appreciate the dealership not responsive to my needs regarding the $40k+ purchase I just made from them.... I see that there are plenty of good ratings... maybe those clients got new cars and didn't have problems. If you're buying pre-owned... I suggest you work out all the problems before rolling off their lot... cuz it doesn't seem like they're interested in solving anything after you sign the paper. Hope this helps any prospective buyers....
