I think you make some great points. I would add a few things. I had my car tires replace by a company that has a truck tirevan.com and comes to your home or office. The cost was more than it would have cost me to wait at a dealer which I gladly paid because of the convenience and scheduling issues. The work was professional and the driver used to work doing the same thing at a retail location and it was easy to see why, for him, this was a much better job. So the ingredients were there to make the service successful. It was a niche though and certainly wouldn't apply to something which (as you say) needed more parts and equipment (not to mention the pricing which works well if you have a high end car but not necessarily with the Chevy crowd.) The other issue to consider if doing a business like this as a "business" is the tax aspect. No doubt the guy coming to your house not only was taking a hit financially but was also making those dollars go further by not (speculating) paying taxes on any income (just like cleaning people that work doing that on the side or a handyman or anyone in a "cash" business). I don't know that for sure of course. He could have reported all that income. But from my experience (and I'm sure you will agree) probably not.
