Very few accessories add value for sale price above the cost of the accessory. If you had to put a new engine in, going slightly bigger tends to pay off an most machines. The winch and roll bar are good to have in the machine, although they basically just help sell it better. When I build a machine I don't intend to keep, I sell off all the other accessories separately to maximize what I get out of it. Unless you go all out and make it into a stereo/light factory on wheels like the razor guys do, it's best to keep it clean and factory looking. People don't mind factory options, but a whole bunch of bolt on stuff tends to turn townie real fast and tends to scare most buyers away.
l like to buy stuff and no I don't do payments!
