Great experience
On October 28th I went to prestige lexus of Ramsey in new jersey.I met with a sale associate by the name of Steven Glenwick who provided excellent customer service he was patient, attentive ,informative. Steven went above and beyond to assist me in selecting my future vehicle. Everyone that assisted me that day were very professional and made me feel comfortable with my choice. I highly recommend Prestige lexus of Ramsey for anyone who is looking to purchase a vehicle. Thank you Marlene.
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

They sold me a 2024 Honda Accord.
They sold me a 2024 Honda Accord. Window sticker brand new was $36,000. After their fees (Which they did have guys) taxes, dmv and state fees.. we ended up paying $33,000. $3K more than originally listed price. This is still a fair deal. The vehicle had 1.5K miles only on it. Therefore, i am ok with saving $3K-$5K all day. Because new car would have been window sticker plus tax etc. also they are very friendly. The guy in the front knows how to work magic
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.

Luis, my sales rep, was helpful and professional!
I recently had a great shopping experience at European Masters with a salesperson Luis. He was very courteous and professional, obviously having customer`s best interest in mind. I initially contacted them over the phone and spoke to melissa, an internet sales rep. She politely answered all my questions and made an appointment for the following Monday. Upon arrival a vehicle of my interest was all prepped and shining. All in all I did spend there quite some time including a test drive, applying for financing, which turned out to be of better terms than my own that I previously was approved for and signing a contract. At the end of the day I drove off in my new car and was very satisfied with the process. Being a 3yr old the car had a highway mileage in Pennsylvania and drove and felt like new. Before this place I shopped in two other dealerships in Long Island and they both felt very disorganised and unprofessional. This place has a great selection of premium higher-end European cars, mostly BMW, Benz, Porsche. The condition of each looked top notch. And best part was that they walk their talk by following their promise and reconditioning some worn off part that didn`t look the best. Thank you, guys, thank you, Luis.
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.

A very friendly and honest team .
I brought my BMW X5 from this place I must say my experience with these guys especially Branden was very professional, I found these guys has being trust worthy and very cooperative the went beyond the closing time to make sure I got my vehicle the very day even though I got there around 1& 1/2 hour before closing time ...I got there @ around 6:25 pm and the was supposed to closed @8pm...Thanks to Branden and José ( I hope I got his name right) And finally and most importantly the price that the advertised for their vehicle will be the price you will pay , not like others who will tell you the advertised price is after you pay down 20%..I will definitely recommend North Star Mitsubishi to you.
