Nothing big, just having regular maintenance. This has been a great car. I leased then purchased it from Colonial and have been happy that I did. All set now.

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 👍🇺🇸
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

They are fantastic
I purchased a 2008 honda crv67,000 miles. I thought maybe I had no chance to get into this Honda because of bad credit. But they assured me if this is the car I want they would make it happen and sure enough it did. The next day I was in my car and very happy. They were understanding, caring, helpful. They made sure the car was in mint condition when they gave it to us. It is running beautiful. I am so glad I went there. I would buy another car there in a heartbeat. They were absolutely wonderful. Thank you car max for making are dreams come true.

I couldn’t be happier with my experience at Richards Motorcars, mainly due to the GM I worked with, Joe, who was great. He was prompt and very easy to communicate with over the phone and via texts. He answered a lot of the questions I had before I even made it to the dealership. I made an appointment, checked out the car and was able to do the test drive, fill out all the paperwork, and complete the purchase in a little over an hour. I couldn’t recommend the dealership more.

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!

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.

Great dealership.
Great dealership. High quality used cars surpassed only by their high quality employees. Salesperson (Alex) and General Manager (Taylor) were great. Taylor is absolutely the best person to deal with. Honest, straightforward and he truly wants to get you a vehicle you love. He's not just trying to sell you a car. He is trying to make you love your purchase.

?????????? 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!
