After getting the complete run-around and dishonest estimates from other auto shops, it was such a relief to find HTC Auto Repair. They were communicative, honest, thorough with their diagnostics and incredibly reasonable in terms of cost. I will absolutely be back and recommend them highly to anyone who is looking for an excellent and trustworthy auto repair shop.

Great auto shop. I've taken my Honda Odyssey and Hyundai Kona to them, and it's always a great experience. Honest work and prices. Their appts fill up fast because they are very popular. Schedule your work as soon as you know what you need!

Had a really good experience buying a van here. The van was clean, well taken care of, and exactly what I was looking for. Everyone I dealt with was friendly and helpful, and they made the buying process quick and straightforward. I also felt like I got a really fair deal compared to other places I had looked at. Definitely happy with my purchase and would recommend Royal International Auto Specialists to anyone looking for a vehicle.
