The staff are always friendly and knowledgeable quick to help and funny. I have always been treated with respect and dignity no matter how much dirt I was wearing. I definitely recommend this place!
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Working with Drew at Briggs Nissan of Manhattan made the
Working with Drew at Briggs Nissan of Manhattan made the car-buying process remarkably smooth and stress-free. From our initial interaction, it was clear that this dealership operates differently—prioritizing genuine relationships over high-pressure sales tactics. Drew took the time to understand our needs and guide us toward the right vehicle, without ever making us feel rushed or pressured. In the end, we felt confident that we reached a fair and mutually beneficial agreement. Gabe in the finance department further reinforced the dealership’s commitment to a seamless experience, handling everything efficiently and transparently. If you’re looking for a dealership that values trust, respect, and long-term relationships, I highly recommend connecting with Drew at Briggs Nissan.

Got a great deal on a Toyota Venza at the GM Dealr
They let me have the car for a night before deciding to buy, they came down on price with a very reasonable offer without having to really negotiate. The car was very clean and they gave me a full tank of gas and offered to do the next oil change for free. Brandy Bartlett was friendly and easy to deal with.

First time we’ve ordered a vehicle sight unseen (except for photos) from out of state. Everyone at Midtown Auto were excellent to deal with and made the process extremely Easy. We we first impressed by their ability to find low mileage vehicles and then sell at such a reasonable price. When we received the car, we were impressed that it looked better than the photos and was in pristine condition. It was also full of gas and recently serviced….nice touch. Shipping was easy and FAST. We are delighted with our purchase and would look to them again in the future.
