I would not let this guy work on a peddle car, much less an actual motor vehicle. Took my sons Infinity in for a steering problem. Not once but three times. Every time it was something else causing the problem. First it was the belts - replaced them. Second it was the steering rack because there was metal shavings in the fluid tank.- replaced power steering rack. Third time he replaced the power steering pump (actual cause) He may pull the wool on others, but I can tell you this guy could not diagnose a flat tire.
