Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

I want to acknowledge Craig S.
I want to acknowledge Craig S. and Adham..they helped us so very much to solve a dilemma! They both went above and beyond to facilitate a great result. We recommend them wholeheartedly.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

i learned my best approach would be going to an
i learned my best approach would be going to an authorized dealership. i knew the car year & model that i wanted. i started compiling an excel list with all the car details. i google searched all mercedes dealerships starting in NJ (figured used car conditions there would be better) & noted all the mileage, prices, interior/exterior colors. i went through all of them, & wasn't too impressed & seemed a bit out of my price range for good mileage. the very last dealership i came across was Silver Star Motors in Long Island City. i checked their Certified Pre-Owned List & they had 2 exact options that i would be extremely happy with (light beige interior - which was harder to find!). the mileage & price for both options was a total steal compared to all the other dealerships.. a steal deal by far! I sent in on Sunday (they were closed) the submission of interest to schedule a test drive. I got a phone call from a rep at Silver Star Motors on Monday morning, who eventually connected me to Diana Sokolova. She called & texted me, first making sure that they actually still had both cars. She was very friendly, professional, direct, and prompt with all the replies. Quickly confirmed that both cars were indeed in store, & that i could come in to check them out. once i got there, she immediately welcomed (i didn't have to wait an hour or so like the previous experience at the private dealership), & took me straight to the cars, which were side by side next to each other. i already had a preference between the 2 options, & was able to test drive the main preference in no time. they had to shift about some cars to bring it down, i was very surprised how fast it was done. Diana was very knowledgeable & answered all of my questions with assurance. She definitely also helped pace out the test drive longer so that i could feel extra confident that the car in test was the one. she never rushed to end the test drive, much appreciated! After the test drive, i was certain to purchase. The price was exactly as advertised, no hidden fees, or anything. They advertised that as such, truly is the case.. again no hidden fees! I wasn't able to get the price down any, but the price was already so good. Great price, unbelievable mileage, perfect condition as used. The car was practically new! After finalizing, Diana was amazing once again! i had to call to set up and purchase car insurance, she helped make that process extra easy and smooth. With that done, i had the chance to drive home with the car right away. I made a request on numbers that i like for a license plate, & by luck it all worked out with the timing because of Diana's handle! Got exactly what i wanted! It was getting late, Diana & the whole Silver Star Motors team was indeed able to get everything in order at the end, & i was able to drive the car home on spot! (otherwise would've had to return the next day) I'm a beyond happy customer at Silver Star Motors; & I'm still completely grateful for Diana's amazing help with the 1st time purchase! If I'm ever back in market, they have my complete loyalty - will go directly to them! Diana is the best! Can't thank her enough! Hope my review is helpful! Diana + Silver Star deserve it!
Great car!
Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

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
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.

My overall experience with Deluxe Auto Sales (DAS) My
My overall experience with Deluxe Auto Sales (DAS) My overall experience with Deluxe Auto Sales (DAS) has been positive, earning a solid 4-star rating. However, the delays in shipping gradually dimmed the shine of that positive review. Carlos and Shane were the main points of contact throughout the process. Their availability, particularly Carlos's 24/7 readiness, was a standout feature. Communication during the initial stages was seamless, and the transaction felt smooth and trouble-free. The process took a turn when two issues arose: discovering a damaged trim piece and delays in shipping the car. Initially, the experience was almost flawless. The website provided detailed images and a 3D view of the car, and the paperwork process was swift. Despite some trouble with the online application service related to a password issue, I managed to resolve it after a few attempts. The car was officially mine over two days, November 7th and 8th. Choosing Ally Bank for the loan saved us a few tenths of a percentage point on interest compared to our local credit union. Now, onto the negatives. From November 8th onward, I received little to no information about the arrival and replacement of the damaged trim piece. Responses like "not sure" or "I don't know" were common. Shane, who was supposed to handle this, didn't communicate the status effectively. Shipping delays were also frustrating. The first delay on November 13th was due to the driver's truck breaking down. On November 15th, Victoria from an unknown shipping company informed me that the car would be shipped. Communication from both companies that day was poor. A request for an SS-4 form from DAS was apparently unmet, leading to the cancellation of that company and an overnight wait. On Saturday morning, November 16th, a group text from DAS at 9:26 A.M. informed me of the car's shipment. At 4 PM, I texted Carlos to confirm if the car was not coming so my wife and I could go to dinner. His response was, "Yes, go to dinner. If I have to drive the car to you myself on Monday, I will." Ultimately, a company was hired to tow the car, but there was no plan to return my old car. This lack of planning reflected poorly on DAS's overall service quality. Despite these issues, the car itself is immaculate, meeting or exceeding my expectations. It shifts like a dream. For future improvements: In group texts, DAS staff should sign off with their first name to clarify who is responding. Keep customers informed. Silence creates anxiety and frustration. Provide regular updates on ongoing processes to reassure buyers.

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!!

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.
