Buying at TSF Auto was a pleasurable experience.
Buying at TSF Auto was a pleasurable experience. The cars were sweet and the prices were great. I would like to thank my salesperson, Egor (I'm not sure how to spell his name), for his guidance. He's one of the 'good-guys'.
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

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.
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 recently purchased my 2024 Mercedes-Benz GLS 450, and
I recently purchased my 2024 Mercedes-Benz GLS 450, and once again, Ahmed Abdeldayem delivered an outstanding car-buying experience. This is the fourth car I’ve purchased from Ahmed, and every interaction has been nothing short of exceptional. Ahmed’s professionalism, transparency, and genuine commitment to customer satisfaction make him a true asset to the dealership. What keeps me coming back to this dealership, however, isn’t just the incredible sales experience—it’s the amazing service department. Chad Kaplan, my service advisor, and Annmarie Albaro, the service department manager, are simply the best in the industry. They consistently go above and beyond to ensure my vehicles are well taken care of, providing prompt, efficient, and top-tier service every single time. If you’re in the market for a Mercedes-Benz, look no further than Ray Catena. Whether it’s working with Ahmed Abdeldayem for your purchase or trusting Chad and Annmarie in the service department, you’ll experience unparalleled professionalism and care. Thank you, Ahmed, Chad, Annmarie, and the entire team, for always making my experience a memorable one!

A great place to shop for any car
I have to say, this is my 4th stop within 3 days before I pull the trigger on the 2020 BMW X5 at Import Masters. I was surprised how I was treated considering I was way underdressed for the occasion. Most sales people would think WHAT THE xxxx IS HE DOING HERE LOOKING AT BMW X5. Edwin was very nice and made sure I was taken care of properly. All the staff are very friendly, even the little guys who are cleaning and waxing cars. They gave me all the information I need it on how to take care of the car. I highly recommend the place and make sure you don’t forget to check out and cruise around the neighborhood. You won’t regret it. xxxx a lot better than some other places I have been to. I advise you to make an appointment before coming in so they can bring it to the showroom. They have so many cars that almost stack on top of each other.

Caldwell Mercedes is great
I purchased two Mercedes Benz' in Two years from Mercedes of Paramus; major mistake. Not only were they a ripoff, they had a very low rating with the BBB. I reached out to Mercedes Corporation and they don't stand behind the customers as well. Luckily, a friend recommended me to Caldwell Mercedes Bendz. They were professional, honest, polite and understanding. Caldwell was able get me out of my bad deal and into my dream car. I almost gave up on Mercedes in general but Caldwell has renewed my faith in the brand.
