Top salesman with a reputable dealership !
I have been purchasing MB automobiles from RVC MB since the 80’s .. I’ve always used the same salesman , Mr Tom Ahrens . Tom has always ensured that my new car purchase goes as smooth as possible .. I’ve always shopped price prior to making the deal - Tom has always beaten the competition prices - a great car coupled with a smooth transaction and a caring salesman working for a reputable dealership works for me !!
The features are amazing,stylish .
Great driving comfort,loaded with features. Safety is definitely a priority with the MB engineering . I have leased a total of 4 Mercedes and totally satisfied with every single one.

Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

The entire dealership staff at CPM was incredibly
The entire dealership staff at CPM was incredibly welcoming, making the process smooth, efficient, and completely hassle-free. I got my Jeep Compass Latitude from them, and the experience exceeded my expectations. If you're looking for a top-tier car-buying experience, I highly recommend CPM and working with Jeremy - he made everything seamless and enjoyable.
Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

I recently purchased a pre-certified Mercedes-Benz from
I recently purchased a pre-certified Mercedes-Benz from Victor Varga, and the experience exceeded my expectations. From the moment I walked into the dealership, Victor demonstrated professionalism, transparency, and a genuine passion for helping customers find the perfect vehicle. He provided detailed information about the car’s history, inspection process, and certification standards. Every question I had was answered thoroughly, making me feel confident in my purchase. The car itself was in immaculate condition, exactly as advertised, and came with a comprehensive warranty that added peace of mind. What stood out most was Victor’s dedication to customer service. He guided me through the financing process with clarity and ensured all paperwork was handled smoothly. Even after the sale, he followed up to make sure I was satisfied with my purchase. I highly recommend Victor Varga if you are looking for a trustworthy and knowledgeable professional to help you find a pre-certified Mercedes-Benz. His commitment to quality and customer satisfaction is unmatched.

OI'm really happy with the lexus I bought. It's exactly what I was looking for. The initial part of the process was smooth, and the salesperson was helpful. The only slight snag was a bit of confusion regarding the final delivery date, but it was eventually sorted out. Overall, a good place to buy a car.

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.

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
