our best car buying experience ive ever had. made the process hassle free and were very helpful and friendly.....will be a return customer for sure!
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Salute to Mr. David Garcia, MBenz Sales Associate
I highly commend Mr. David Garcia for his knowledgeable, professionalism and caring follow-up manner in which he demonstrated, during the purchase of my Mercedes Benz. Although I was disappointed in dealing with the sales/financial manager for his inappropriate, condescending attitude, Mr Garcia was able to diffuse our differences and finalize the purchase.

Saw the g class bought the class in less than 3 hours. Alfonso the sales guy was a PRO! He did FaceTime walk around. I've been shopping for weeks and this dealership had it priced right. From NY to Texas. Will let you know about the shipping and final outcome and one last point NO hidden xx fees like doc destination or whatever. This is a first class Merc dealer.
