Here's what I want: To take my car to a gleaming, state of the art repair facility with every tool I could ever need, staffed by auto mechanic "coaches" who will help me repair my car myself.

1. Tool theft. Anyone that's ever done anything Blue Collar will know that tools evaporate as soon as you turn your head.
2. Failure to fix. Cars end up taking up space due to their owners inability to fix and/or put them back together. Then it's up to the 'coaches' to become lowly paid mechanics and put the thing back together for them for next to nothing just to get the car out of the garage.
People have been trying this idea since the 80s. Never worked before and it probably never will.

Pretty much explains it.
