Wesley was very professional didn’t question my offer
Wesley was very professional didn’t question my offer brought it right to sales manager. Negotiation was smooth in the end I paid what I thought was a fair price and got a powertrain warranty thrown in. They delivered car promptly inspected and filled gas tank. Very positive experience no pressure. Thank you guys at Autobahn Westborough.

I would like to thank the service department for honoring
I would like to thank the service department for honoring my rim warranty. I brought my truck there while I was getting new tires and wanted my rims to get refinished at the same time because I paid for the warranty when I purchased the vehicle and the service wasn’t available at that time. They told me to bring it back. I brought it back almost a year later and my warranty was up. They completed the rim repair and I didn’t have to pay for the service to be done. ZERO cost to the customer!!!! Nucar puts the customer first!!!! Thank You again for the service and consideration!!!!! I will continue to purchase vehicles there as well as getting them serviced 👍🇺🇸

?????????? 5/5 ? Outstanding Experience from Start to
?????????? 5/5 ? Outstanding Experience from Start to Finish! I recently purchased a Hummer from GMC and had the absolute best experience I've ever had at a car dealership. Jacob M. was incredible to work with?professional, friendly, and genuinely dedicated to making the process smooth and enjoyable. From the moment I arrived, Jacob made me feel welcome and informed. He answered all of my questions, took the time to explain everything about the vehicle, and never once made me feel pressured. His knowledge and honesty were a breath of fresh air. I also want to give a huge shout-out to the entire team?from sales to financing. Everyone I worked with was courteous, efficient, and made me feel like a valued customer. They helped me pick out the perfect vehicle and made the financing process simple and transparent. If you?re looking for a top-notch dealership experience, I highly recommend stopping by and asking for Jacob M. and his team. They made this Hummer purchase one to remember!

I recently purchased a used vehicle from Imperial. the salesman Gabriel Borrero was amazing. I told him my finance limit and he did not try to sell me a vehicle I could not afford. Ahmad Al-jallad worked for 2 days to get me financing with my low credit score. They will be my go to dealership from now on.

I would like to especially recognize my Sales Rep, Jeffrey Jones. He was not sales aggressive, very down to Earth, and made me feel lease nervous. He was honest. Additional he worked with Peter and Sosa, who were also great, to get me into a new car. I left a 5 star rating on Google.

Purchasing my Jeep Grand Cherokee Limited from Imperial
Purchasing my Jeep Grand Cherokee Limited from Imperial was so easy. They are only 10 minutes from my house and had at least a dozen Cherokee L's for me to look at. Our Sales Agent, Kelsey Legeny, knew all about the various models and features and let us test drive a few. She gave me a great price and even extended the factory warranty as a bonus. I paid on Saturday and picked my new car on Tuesday morning. They took care of all the RMV paperwork and worked with my insurance agent. I didn't have to do any of that. When I picked it up, it was detailed to showroom condition. Very happy customer!
