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.
Love my Mercedes
I have been driving Mercedes Benz s class vehicles for over 10 years, traded every 3-4 years and have been very happy, always have them serviced at the dealer, always received a loaner, no complaints.

Owner - brought car in for routine service
Maintained their always high standards in the midst of the coronavirus challenges. Excellent service for the car. Easy scheduling and quick turnaround while fully respecting the additional risks that the virus posed in the pick up and delivery of the car. They will always get my business.
An Absolute Dream
I have owned 6 S Class (SonderKlas) cars in my life and each and every single one has been problem free and a pure joy to own, drive, and admire. The 2021 S580 however.. Well this car is truly something special and not an incremental upgrade! This thing is crazy

Steven David Benzel Busch
I rarely write reviews and for the very few times I have done so in my life time, it was always to point out a bad service. HOWEVER. I had exceptional experience purchasing my E400 Coupe with Steven David from Benzel Busch. Since getting my first license back when I was 16, I bought and sold 10 different cars and Steven by far exceeded any of the sales person I have worked in the past. He was very responsive to all of my emails and phone calls. I almost got a reply back within 5 minutes from sending an email and we had many emails back and forth as I was purchasing a vehicle out of state. He was very detailed and truthful when describing a vehicle that I was purchasing. There were few times where he reached out to me first on items normally you wouldn't expect sales person to. Thank you, Hyunbin

Second car this year at Pristine!
This is the second car I purchased from this dealer. In March, I purchased a 22' Outlander SEL for my company car. This week I went back and purchased another 22 Outlander SEL for my wife! Travis, our salesman, went above and beyond answering my questions and finding the perfect trim and color for our new car. I was pleasantly surprised at how courteous and professional Ryan was when it came down to locking in a good price and a monthly payment I was comfortable with. This dealer as a whole has been nothing but OUTSTANDING for me and my family. This is my 8th Mitsubishi purchase over a course of 20 years. I've been to my fair share of Mitsu dealers in the past and can honestly attest to their professionalism and outstanding service.

Great service at North Star Mitsubishi
Ray Valencia helped me with my car search at North Star and helped me lease a new Kia Niro. He was very patient and worked with me until I found something I liked and could afford. If you’re in search of a used or new car, North Star will work with you to find a car in your budget!

I had a great experience.
I had a great experience. Service advisor pointed out that I had a 1 year warranty on the tire that needed replacing. Also, front brakes were serviced and covered under maintenance plan. The customer waiting area is very pleasant and the work was done within the time estimate provided. Have been very happy with this dealership.

Andrew P was our salesman and he was very friendly and knowledgeable. He wasn’t pushy at all and helped us get the best deal possible. Everyone we dealt with at Pristine was a pleasure to work with. I would recommend this dealership for your next car purchase.
