 Trustindex verifies that the original source of the review is Google. I brought my car to HTC Automatics after another shop gave me a quote that was almost double. I figured it was worth getting a second opinion, and I’m glad I did. The team took the time to explain what was actually needed, got the car fixed quickly, and saved me a lot of money in the process. No upselling, no pressure, just honest work at a fair price. If you’re dealing with car trouble and want a shop you can trust, I’d definitely recommend giving HTC Automatics a call.
