My Porsche journey began early Feb 2026 with a call to
My Porsche journey began early Feb 2026 with a call to Porsche Sewickley to inquire about a car that was being advertised on CarGurus. Without delay, I was connected to one of the Sales Professionals, Mr. Bob McLaughlin. Out the gate, he was consistently professional, responsive, and thorough in addressing all of my questions and concerns. A few wks later, I made the 4-hr drive from the DMV area to Sewickley to see the car. After the test drive, I knew it had to be mine, but needed time to make an informed decision. He never applied pressure during this process and was incredibly respectful, as he understood that purchasing a Porsche would be a significant investment for me. He and I did the dance for a couple of wks until I decided to secure the car. Every step of the process was smooth and painless. Bob connected me to his team?s Finance Manager, Mr. James Lumbantoruan, who was knowledgeable and guided me on all things finance-related. I also enjoyed chatting with him about Beyonc�. When I returned back to Sewickley to make the purchase, I was welcomed at the airport by their friendly and knowledgeable driver, the ?other Bob.? I cannot tell you how exceptional my experience was from first contact. Everyone that I encountered, to include the Sales Manager, Mr. Dwight Woodside and another Sales Professional, Mr. Stephen Overby all created a personalized small business vibe. The team?s passion for the Porsche brand was evident throughout. Thank you again Bob for taking such great care of me during the process and providing that personalized touch. I look forward to returning in the future! - Chanel M.

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.

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
