that was one one my business ideas i have had for a while, nothing like that exists for civilians. if i got an old heated warehouse in the city and put a bunch of lifts and tools and a tech or two on staff, i think i could make some money. people who live there dont have a choice but to take it to a mechanic and they charge to much and you never know what kind of service you are going to get
A lot of that is because of EPA regulations, shop insurance etc.
I had the same access while at Ft Drum. Man I loved taking my cars there in the winter time, throw em on a rack, change oil, change tires, etc all for next to nothing. Now I have to do it in my cold *** driveway.
i wouldnt even look at houses with no garage or barn, they are pretty expensive to add later.
as far as insurance there must be something like business insurance, or school type insurance it would be like that. im not sure if you could just sign a waiver before use like we do in the atv club or something like that
