id give him $60 for effort, $100 for the frame, $100 for the engine, subtract $75 for being a try hard and making it look like its old when its just lame, and take away another $75 for attaching that stupid thing to the front forks because hard as i try, i cant see how it serves any real purpose. i seriously hate things that attempt to look like what they are NOT. so whats that? $110, and then i still wouldnt want to ride the stupid looking thing...
now, if it had a genuine whizzer engine in it, or was handmade like something back then would have been, the front forks where genuinely pivoted and sprung, and it didnt just look lame, well, then i would say $3000 is not only a bargain but unbelievable...
as it stands...let him sell it to a moron with more money than sense. move on my good sir, move on
im sure, given my critique, you could do better
