I have had thorough work done on my Toyota Tacoma ever since I left a competing, larger, certified auto repair shop in town. The previous competitor, as an example, was sloppy in completing their work requiring that I RETURN to clean up and restore the access point used for repair. Mohr's has always returned my Tacoma in good condition and have given me a better estimate/final bill that was more in line with my budget than the certified repair shop has. The certified shop continues to try to bring me back for "certified" work! Does certified mean sloppy and incomplete?
