Looking for a reputable mechanic in Dallas

I am attempting to purchase a car at a dealer in Dallas, and I live in Seattle. The car is currently at a dealer, but since I have never bought via the internet I am looking to pay someone a reasonable rate to go and evaluate the car for me. Does anyone know of a reputable mechanic near Cowboy Toyota in Dallas (I30 and Buckner Blvd)? Thank you in advance!
