Honestly?
First I thought, "What a heavin' piece of crap!"
Then I looked in the mirror, and realized that sometimes a beat-up exterior hides a well-oiled machine.
Anyway, how are you gonna use it HR? I don't use excavators much except for stuff I probably shouldn't even waste my time doing, but I'm told once you dig a pond with one, you'll never go back to the shovel. I could see roughing out tree holes with it too. But moving dirt, I would go with a skid-steer.
And since my mechanical skills are rudimentary, I would never feel comfortable buying a machine that looks so, shall we say, "used".
