For the first one, I would say you should be able to get 1500 for it if you find the right person, I sold a real old Yamaha Blaster I had last year and got 1 grand for it, so you just look around for the right buyer and you should easily be able to make enough to get your money back at 1.5 grand.
The second one, is it all stock? Also did you buy it for 5,000? Or is that just the brand new price?
