If anyone gives you more than say $2200.00 , they fell down and hit their head.
It's dirty as heck. Ball trails everywhere, I could go on.
$4100 brings a full restoration and shine that is worthy of being called sexy.
You may want to take a step back and reevaluate the condition of the machine. Go take a look at the archived sales to see condition vs price.
Good luck
