In Europe, scrap prices are between 110 ("dirty") to 180 EUR ("clean") per metric ton (1000 kg or 2200 lbs, when the ##$% will you guys shift to world standard, that is, metric).
That means that a 10 ton truck will bring something around 1500 EUR or 2000 US$$ scrap price. US will be a bit different, but even there, with a purchase of a running truck for $1500 even without title, it is worth the risk.
Off course, getting the title is much more better, but I would not let that stop me. If nothing else, you can recoup your investment through parting the truck and, of course, having a lot of fun on this forum.
