When I first started Kubota stuff, I got to learn about sales stuff. Cause, well, I thought I wanted to be one. (nope! I'm too technical...had to go to the shop).
Anyway, one of the things that that particular dealership had was a checklist that the customer signed. On that checklist, which was pretty simple, it basically says "I received the following...."--which was, among a few other things, the PDI sheet. You want to know how many times I saw people just sign stuff and not think about what they were signing? When I bought a new outboard a few weeks back, the dealer had me sign a few things....and I still remember almost every word of every document. Ya gotta pay attention to this stuff.
