Experience from my years in the automotive tool biz: The tool wagon biz is a very expensive way to do biz. The insurance on a mobile store full of tools is very expensive, easy to steal, lots of ways to damage people/things, etc, and can never do the biz of a good box store. It's not really sales, easy to put tons of tools out there, the hard part is getting paid, more like a pawn shop, loan shark biz, customers skip with paying, etc. In every way, fuel, time, etc, more expensive than a store front.
If you are using the service, weekly visits, financing, etc, maybe (not likely) worth it. All of those inefficient biz model costs are built into the mobile tool biz, the tool price is hugely inflated by them. Just because you pay the most $$$ for them, is not necessarily an indication that they are all the best or others available maybe just as good, at a fraction of the price.
Many of the wagon tools are private labeled from other manufactures, sometimes more highly polished, etc, but always with the significant wagon markup. If you don't need the financing, can just about always find great quality tools at a fraction of the price.
The wagon warranty is great, but if you don't have the service, it can be a pain to get it done, if you have to send them in, might as well shop amazon? Most of the good tool companies have the same warranty and for most of us, much easier to walk into the store and get it taken care of, than chase a wagon.
