I guess I don't trust mechanics since every minor repair always ends up with repair requirements of $1K. I know that can't happen every time.There's no problem having a mechanic of your choice (or yourself for that matter) provide regular service or repairs, though the intent is for Pep Boys to be be specifically trained on the Elio, I think a good mechanic should be able to work on the vehicle without too much problem, though they may need to weld up their own rear wheel jig to get the vehicle up on a lift.
I half expect the "fleet" purchaser in December to be Pep Boys so that they can train up their guys and have a bunch of mechanics drive them around and give some focused feedback. Who knows.
