Buying and service experience
Bought our 2022 Passport at Boch Honda West and felt no pressure from Mike or Rich during the process. Service over the past year has been seamless and stress free. Very accommodating when a timely recall was needed. Supplied a rental without issue.

2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Genuine interest in pleasing the customer
As first-time customers, our experience at Mercedes-Benz of Portsmouth was exceptional right from the first phone call. I told my initial contact (Bethany) what pre-owned vehicles I was interested in, and a time I was planning to visit. When I arrived both vehicles were parked next to the show room waiting. We were greeted by Nick in Sales, given a brief overview of the 2 vehicles and then given the keys to take them for a test drive. For all 3 of our test drive visits the vehicles were waiting, normally running, and always nice and clean. We were never rushed, and there was never any pressure to choose, or make an offer. All questions were answered quickly and thoroughly and all information about the vehicles and vehicle histories was transparent. We were never steered towards any particular choice. Negotiations were quick and straightforward. We picked up the vehicle on a very cold day. It was sitting in the showroom perfectly detailed and all warm. Everything promised was delivered - even the front Weathertek mats! Finalizing the deal was a breeze (thank you Paul) - again very straightforward and transparent. These folks like what they do and it does seem they are allowed to do whatever they can to accommodate their customers. Very nice experience!
GLC43AMG
I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

Great Service and Attention to Detail !
Bethany, Tuck & Paul created a great, honest and personal experience at Mercedes-Benz of Portsmouth and my purchase/trade was top-rate in all respects. Your dealership had a very unique used car in stock. I came from out of state and each of you exceeded my expectations on the service, attention, quality and condition of the car as well as your preparation and welcoming treatment of me on site ! Thanks again ! Jack L. -- Virginia
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

I would like to thank Randy Wheeler for his very professional and helpful assistance while we navigated the purchase of my daughter’s first car for her 16th birthday. Randy was knowledgeable and accommodating throughout the process and was instrumental in coordinating all details for us to allow for the surprise reveal of the car to my daughter. Thank you Randy! I would highly recommend anyone looking to buy a car to work with Randy.

Gold star treatment
Went to 3 other dealers before being reccomend to matt Harris and knew instantly it was our last stop. We has been treated like xxxx at the other dealers. 1 lied to us and another told us he would not replace bald tires on a 2 year old luxury vehicle. The second we met Matt we knew we were In great hands. My fiance got the Mercedes she wanted at a fair price and the vehicle recieved everything it needed in the shop before we looked at it. The finance guy treated us like human being and never once felt like I was being had. Oh I forgot to mention that I sold cars for the last 17 years so I recognized great people right away. We will always be loyal to Matt and appreciate everything he did for us
