Great Boston BMW service!
Since the 90’s I have owned 5 used BMWs. Once you drive them you don’t change horses. I have been bringing them for service there since 2009. Great service and no need to wait for parts as in other garages. They are stocked. And they treat the earlier models (older) BMW customers as well as they treat someone who is either buying a brand new one or has a new one. They run the cars through the wash when finished and wipe down the interior and vacuum - and it is a very classy touch. The wifi is strong so you can get work done when you are waiting for a repair. It’s painless.

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.

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 recently purchased a 2016 GMC Sierra 2500HD from Car
I recently purchased a 2016 GMC Sierra 2500HD from Car Five in Nashua, and the experience was seamless and stress-free. The buying process was straightforward with no unnecessary delays, making it one of the easiest car purchases I’ve ever had. There were two clear fees disclosed upfront: a $795 administrative fee and a $699 paint protection fee, so everything was transparent. My salesperson, Joe, was incredibly professional. He listened to my needs, answered all my questions about the truck’s history and features with complete honesty, and helped me feel confident in my choice. There was no pushy upselling, just genuine expertise that made the experience enjoyable. In the finance office, Stephen was equally impressive. He handled the paperwork efficiently and explained everything clearly without any pressure. It felt like he was there to help, not to sell. If you’re looking for a reliable used truck, Car Five in Nashua is the place to go. Great team, transparent process, and an excellent vehicle. Highly recommend!
