Im a UTI graduate . Did the Nissan msat. And am now a line tech for Honda.
Their base course if informative and you learn some basics. Its a great way to blow 30k and not learn much. ( especially if you already have a mechanical background)
Theyre msats ( manufacture specific advance training) programs are 100 times better than base UTI. Thats where you actually learn diagnostics , troubleshooting and system operations.

My honest opinion is to start at a dealership and work your way up. 90 % of the dealers you get hired at after completing UTI start you off at the bottom regardless. Uti isnt as highly regarded as it use to be about 5 years ago.
Save your 30+k and work your way up in a dealer. Also by doing this youll see what this business is really about rather than hearing the fairy tales the recruiters make up .. 100k a year
