I came to Royal Moore to shop for a new vehicle after I
I came to Royal Moore to shop for a new vehicle after I had been deceived with fraud, lies and manipulation by a dealership I had previously purchased a vehicle from in December (Dealership located in Gladstone Oregon, NOT ROYAL MOORE) I was nervous but shortly after arriving to Royal Moore my worries quickly subsided by the absolutely amazing, kind, caring and honest employees that I had the pleasure of meeting and spending the day with. I truly felt like royalty, the treatment was so top-tier I don?t think I will ever step inside of another companies dealerships again to purchase any vehicle. My salesmen, Christian (Royal Moore Mazda), was the kindest, goofiest and most enjoyable person I could ever have to help me with my journey of purchasing a car. He was so knowledgeable and created such a huge impact on me while creating a bond of friendship and trust as well. I could tell that he wanted what was best for ME whether that meant purchasing a car from him or anywhere else, the support he gave towards my decisions did not go unnoticed and I appreciate him wholeheartedly for that! If you want a caring and thoughtful car salesman who doesn?t pressure you at all, then Christian is your guy! Like please please buy a car from Christian, you will not regret it! We laughed literally all day together and it was the most wholesome experience I?ve had at any dealership ever. Truly someone I am so excited to come back and visit at Royal Moore when I come in for future service needs on my vehicle? Or whenever I feel like wanting to brighten my day :) Omid, ohhhh Omid, what an amazing GSM (Royal Moore Mazda).. he truly helped me get the best deals available through the dealership on my new vehicle. He knew how absolutely in love I was with the 2026 Acadia and did everything in his power to make sure I left the dealership that same day in my new wheels. Also making sure I did not feel overwhelmed by my new monthly payments. I love that he could laugh at the absolute nonsense I spew out of my mouth sometimes. He was a true pleasure to work with and really does an amazing job with representing the company. Finance is such a scary part of purchasing a new car but Nathan (Royal Moore Mazda) really did a great job of rewiring how I feel about finance managers. After a terrifying previous encounter with another dealerships finance manager? Nathan, my mom and me had the literal BEST TIME cracking the absolute funniest jokes together.. I could not have asked for a better experience to replace the bad memories someone else created for me. Thank you so much Nathan, you truly made the day even more special. Also for the record, NATHAN SAID. Last but absolutely not least, if it wasn?t for David, the general sales manager over at Royal Moore Toyota, I wouldn?t have had this opportunity to purchase a brand new car at all. He truly went so far out of his way for me, to help me when I was being wronged by another company, to guide me on what to do and the steps to take to protect me as a consumer after being sold a vehicle with undisclosed major accident damage. With his help and a miracle I was able to climb my way out of a fraudulent bad deal with another dealership. He then referred me over to the awesome employees at Royal Moore Mazda where I purchased my beautiful brand new 2026 GMC Acadia Elevation Black Edition. THANK YOU to everyone who helped me along this journey. I am loyal to the Royal from here on out. The only Company I will give my business to from this point forward!

Just purchased/leased a 2026 Trailblazer.
Just purchased/leased a 2026 Trailblazer. Stanley Thornton was the AutoPlex rep. Very knowledgeable about the brand, including pros and cons. His communication skills are extraordinary. His dedication stems, in my estimation, from his veteran background. solid character, give him a call !!! Dayne Luce.

We've had a great experience with Key Auto Mall GMC
We've had a great experience with Key Auto Mall GMC purchasing our new 2025 Acadia. Brian MacGee was wonderful to work with along with General Manager Theron Maring and all the other great staff. Brian especially has spent a lot of time going over all we need to know about how this car works and has several times answered more questions since we purchased the car a week ago. He helped us purchase new cargo mats and get the protective coatings on the car, inside and out. Brian has been professional, friendly, and so helpful to us. We highly recommend Brian and the Key Auto Mall GMC team and will definitely consider them for our next auto purchase.
