The guys here are very good. They are upfront with time and expectations. Really happy with the repairs on my 2012 Buick Enclave. We recently purchased the Buick from private seller, and 2 months after purchase it started to act up. The power assist code showed and slowed power to SUV, I took it to Parra and they gave me a reasonable time frame and estimate of costs. In the end they were able to fix the one fuel pump that was causing the failure and all has been just perfect. I will go back to Shannon anytime I need honest service with guarentees.
