Trustworthy and Fairly Priced!
Bought Model S Plaid from Duane. Exceptional level of communication. I picked my Brand new Model Y few months back at TESLA and this Car literally looks way better than my new Y. The aesthetic appearance, the cleaning, exterior and interior minor detailing, the shine is absolutely phenomenal. Guy puts his heart & soul into cars collection. I travelled from NY to Connecticut to pick up and all cars in showroom were pristine. Its definitely not Mercedes or BMW level showroom experience (who cares an Air Conditioned office or a snack). Don't get disappointed when you go in person lol. Guy is simple yet dedicated. I got fair value of my Model Y. Smooth documentation/transfer. Duane offered Complimentary ceramic coating as well that no one in industry offers with such narrow profit margin (Just because they do in house detailing and coatings). Car stands out wherever it crosses. Best wishes for Duane and team for a successful business.

Great service!
Great service! Thanks to Power motors and Ivan for the really great service they gave us
Love at first drive
I love my 2020 x3m. I will own this until the wheels fall off and replace it with another x3m. The gas mileage at 19.5 miles a gallon is the only bummer but it’s well worth it.

I had the best experience , Ivan helped me out as much as he could. Nothing was rushed, took his time to see what he can do best to knock some numbers down. Highly recommend stopping by for your new car.
Awesome!!!
I’ve owned a 2020 x3m competition since the month they were released. First let me knock out rough ride thing. If you ride on the stock Conti summer tires all the time, yes it can be rough. I switched to to Michelin all weather after 11,000 miles and it made a huge difference! A much better more comfortable ride Side note: when I would swap Conti to winter tires also a huge difference! The stock summer tires that come on the car are incredible for handling on a track which the car was made for but, the car feels much better with Michelin all sports all seasons. This car makes me happy every time I drive it ! So much fun to drive!

Amazing customer service, recommend anyone to come here
Amazing customer service, recommend anyone to come here and buy there car. Friendly welcoming service
Sedan vs SUV
Absolutely love this SUV. Had a M340i and it was quick, but this X3 M Competition is wicked. Love the quickness and the firm ride. Glad I made the switch. Lots of talk about the firmness and the rigid handling, but try one and see for yourself.
There are 5 matching cars close to your year range.
