I love the "I got a good deal on the internet" trucks or the "This guy I know, knows this guy who can get you a deal", we call them "Restorations in a can" trucks, high hour,low maintence scuff and squirts.
A few I had to go out on had a beautiful paint job, but you open the hood and the truck was never even steam cleaned or blown off.
My company makes a ton of money off these types of trucks when I get to fix them, then on the other hand, when our used truck dept. sells a unit in my area, I go through it with a fine tooth comb and fix everything they didn't fix or thought they'd slide on while the truck is still under our warranty program, keeps my customers happy and keeps me working for them and the Used equipment dept. never knows the difference.
The dash recall program was also done through Nissan on the early LO1-LO2 series trucks, I got the honor of doing about 105 of those that year. Most of them had some type of marking about the hour difference, but I'll bet more of them didn't.

I had a guy call the shop and wanted me to meet him at another location, come to find out he was looking at buying a mid 80's Yale from another company.
I spent about an hour looking it over and told him the bad news,but I saved him from making a costly mistake by buying the truck. And yes, I've been burnt by buying off the internet also,so I've learned my lesson too.
