    Dropped off my car for the brakes to be replaced but through an extensive and thorough diagnostic by the Royson Technician the replacement was deemed unnecessary. They would go on to replace the hardware that failed free of charge! The knowledge and professionalism displayed by Roysons’ is unmatched!

  • We showed up to Royson's from out of state at 4:55pm on a Friday night (they close at 5pm.) Kendra and a team of techs were SAINTS and stayed late on a Friday night to replace our broken alternator so we wouldn't be stuck there that weekend. THANK YOU for being generous with your time to make our trip so much better. Kendra was so up front with us, helped talk us through several options about warranties and got us the best price, and I'm still convinced they undercharged us because they were the least expensive mechanic we had been to after having to visit 3 mechanics on this road trip.

    I've had my vehicle worked on 2 different times in about 3 months. Kendra was/is amazing. She wasn't sure when they could get to it but I dropped it off Thursday night. They had it ready to go Friday afternoon. The second time it was an issue I couldn't describe. My second job is driving a lot and she helped me describe the issue. They worked on my car and found the issue right away! I went to pay and it was less than quoted because this place had compassionate and dedicated people working for their community. I will never forget their service and compassion. Kendra is an absolute asset. Their mechanic is also phenomenal. They have never tried to upsell me and in fact pieced it out so I could afford the repairs on my budget. Thank you Royson's you put other places to shame!!!
