I've used K-Tech twice. The first time with my PT Cruiser that showed a "check engine" light. I couldn't have been happier with the results. The repairs were timely and effective. The car rides as good now as it did when it was new, and fuel economy has increased 6 to 8 miles per gallon. I just brought my 2005 Prius in for its 120,000 mile service and just as before, the service was terrific. The car was ready when they said it would be and it was delivered to my house. They have become my go-to auto repair facility
