Went to look at this M-416 today. Over-all excellent condition. It's all there as far as I could tell. Deck is solid and no holes noted anywhere else. The only things I noticed was the guy cut the rear panel and made a tailgate and hacked it up, one tire won't hold air and it's also missing the serial number plate. What do you guys think? Is the "tailgate" a big negative? Worth $600?
