Quoted from Whysnow:Since this is already sold >>>
I think you are looking at this through rose colored glasses?
I see pitted ramp flaps, a beat up cab that was routed for sure, broken spline on cab, dirty in need of a shop out, rust bolts showing this was in a damn environment (makes we wonder how much pitting and oxidization to expect on underside?), ball trails on ramps.
go take a look at archived ads for some comparison. punch in CP and you will find legit HUO examples for what you are asking. Routed in need of a shop job can be under 4k without much effort.

To be fair, I did the search and found 0 under 4k. I found more over 5k and a couple sold for over 6k with colordmd and some cool stuff added. If you see those sub 4k champ pubs send my way I'm in!
