Simply the best! Our salesman Sam was wonderful, Mark (finance) professional and quick— All around perfect experience in every way! Easiest buying experience we ever had!

We will be back to purchase more vehicles in the future, I’m sure!!
This car is legitimately cool
It?s comfortable, modern, fast, and handles well. Definitely no regrets in buying one. If you?re on the fence about which Audi to get, spend the extra money and get the S6.

I have never written a review regarding the purchase of a vehicle. However, my experience with rime Motorz was exceptional. From my first telephone call with Vinnie to inquire about the Porsche 911 the had advertised, to the morning I walked into the dealership I felt very comfortable this was someone I could work with. I was greeted with genuine smiles and a warm welcome. Vinnie was incredibly professional and obviously knowledgeable about the car. My questions were all answered in detail and made me feel as if I was a long-time valued customer. In reviewing their facility and the beautiful exotic vehicles in their inventory it was obvious this is a high-end company. The actual sales process and paperwork was equally done with detail and integrity. I would recommend Prime Motorz to anyone searching for a quality used exotic car or SUV to contact them!!!

Great vehicles, great people, great service!!!
I never enjoyed buying vehicles but Dan, and Royal Automotive, completely changed my views! I bought a 2017 F-250 at a great/no-haggle price, and couldn't have been happier! A little over a week later... CHECK ENGINE light comes on... you can imagine the feeling! Long story short- ROYAL AUTOMOTIVE has your back!!! Dan immediately showed support and customer backing... And what turned out to be something absolutely no one could imagine happening to a low mileage truck- blown head gasket/potential cracked cylinder! They not only fixed this unfortunate and unforeseen issue, but completely replaced it within one week of the check engine light! WOW!! Dan and Royal Automotive put a new engine for me...completely covered!! This place truly wants to not only see you happy, but keep you happy for the future. I can honestly say for such a big issue on a new-used vehicle, I am as happy as a customer could possibly be. I WILL refer him to friends and family, and I WILL purchase from them again! Thanks again for all of your honesty, patience, friendliness, and all around five-star customer service!! -Frank

I purchased a Chevy Silverado 2500HD from Bob Brown
I purchased a Chevy Silverado 2500HD from Bob Brown Chevrolet on New Years Eve 2025. We had only a very short window of time to get the deal done. My salesman was Nolan Mitchell. Nolan was very responsive, communicated well and was hungry to do business. He handled the sale perfectly! I knew that there would be extra challenges and risk because this was an out of state purchase. I am in Massachusetts and the truck was in Iowa. I bought the truck sight unseen. When the truck was eventually delivered, it was everything I had hoped for. Initially, the truck was missing a spare key and transmitter. Nolan made sure that, in time, I got the spare key and transmitter! Other dealerships maybe wouldn't have done that for me. I think this speaks volumes about their character and how they do business. Other challenges included getting the truck registered and titled in Massachusetts even though it was purchased in Iowa. Mass RMV does not make things easy! Bob Brown Chevrolet's title department worked with me every step of the way to get the truck legal in Massachusetts. Kelcey Firestine in the title department was simple awesome! Thank you Nolan and Kelcey at Bob Brown Chevrolet! A+++++++ Job well done!
