ditto what UD said.
tires? you knew what you had when you bought them. that's on you.
wires, points and plugs and oil change, rad hoses. Plan on doing that at purchase on anything you buy unless you saw it done.
batteries don't last forever.. more of a rental item....
water pump is like clutch. they eventually need replacing.
you didn't go into specifics on the hyds not working.. but if that too is fixed.. sounds like all the major stuff you'd expect has been taken care of.
Again.. ditto what UD said. if you sell that one and get another.. jump right to 55+ and start looking....
