Great Experience!
I had reached out to several car dealers regarding Mercedes and BMWs and Rodni was the first to respond. Even though I live in Central NJ, his prompt response was impressive so I went out to this dealership a few days later. I wound up purchasing a beautiful Mercedes and I'm very pleased with my dealership experience.

Really impressed with this dealership, particularly the service department. I was driving two kids to college, got a flat tire coming across the Tappan Zee bridge, 20 minutes into a 9 hour trip, happened upon them, had my tire changed in under an hour and on my way again. Fast, professional and a terrific experience. I was so impressed, I may have them regularly service my car even though I live in CT.

Awesome Dealership!
Awesome Dealership! I had a pleasant experience at Mercedes Benz of White Plains. Ardit Shabi (Sale Representative) was very professional, friendly, polite and extremely knowledgeable. He listened to what I was looking for and helped me find the perfect car. Bob Binett, the CPO manager, was excellent as well. The help from both of of them, made it possible for me to get my dream car. You both made my car buying experience a memorable one. All of the other staff here were nice as well. I love the 2 beautiful key chains you gave me. Thank you for arranging registration for me. Last time with BMW, I have to do it myself. What a wonderful service! This is a great dealership that you can trust. Thank you so much.

We just bought a CPO 2022 S580 Mercedes!
We just bought a CPO 2022 S580 Mercedes! Joe Horneman was our salesman, and he was an absolute joy to work with. There was no pressure, and he was very accommodating to our needs. We'd been looking around at multiple dealerships and no one treated us like family as Joe did. Throughout the entire process, Joe was patient, knowledgeable and available to us for questions and discussions. This is my 8th MB purchase, and I've found a new dealership to work with, and a new salesman!!

Another Great Car Buying Experience for a New Yorker at
Another Great Car Buying Experience for a New Yorker at LEXUS GREENWICH! I purchased my second LEXUS at LEXUS GREENWICH driving there from NYC! The effort and trip are always worth it as the car buying experience is transparent, comfortable, even pleasurable, informa, unhurried and easy-going. Thus, my second LEXUS purchased here!! Wherever you reside, do yourself a favor and take a ride to LEXUS GREENWICH and speak with Anisa and Art. You won’t be disappointed in the least! Their good faith actions and open dialogue are proof of the pudding!

Excellent selection and service
I would highly recommend working with Ralph Rodriquez at Mercedes-Benz of White Plains. He is very knowledgable about the brand and models but isn't pushy. He made the buying process super simple and valued my time. The dealership has a good selection of certified pre-owned cars at excellent prices.

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.

Thank You Martin and Major World
My experience at Major World was exceptional! My salesperson Martin was knowledgeable, professional, patient and kind. I told him my budget and he immediately brought me to a section where dozens of vehicles were in my price range. He pointed out the ones he thought were the best value and told me why. He never tried to get me to consider something out of my price range. The whole staff was friendly and very helpful. In a couple of short hours they had me insured, new plates and driving home in a beautiful silver 2012 Chevy Malibu. Thank you Martin and the wonderful staff of Major World. Sincerely, Anthony Ferrara
