exchangeable 3 mt 8 mm very clean press brake 4 mt

My apkant is a 3100 mm 120 ton NC laser safe service well maintained machine. I am thinking of selling or exchanging it because I will buy 4 mt. It can be exchanged for a 4 mt apkant, but it can only be exchanged for a clean machine. Also,  open to offers from masters who can extend my machine to 4 mt.
