IMHO, that truck won't sell for that price due to the economy right now. I watch these on fleabay and other places and prices are down. A couple of years ago it would have been worth that $8500 USD. I know nothing about that truck, but just from looking it's an ex-Swiss 404s (wedge shaped canvas roof), probably mid to late 60's, and has not been boogered up by a new owner who had better "engineering" ideas than MB. So many of these 404's get modified for trail or rock climbing, so an unmodified original is becoming rare. Again, IMHO, if it is direct from the Swiss it is probably in excellent condition mechanically, rust free, and is worth the somewhat higher price than a truck that has been modified, even if it does need paint.
