SellMR2

I have a 1987 MR2 (130000 miles) that I want to sell. I have no idea what to ask for it--my neighbor is offering $300 for it but that seems a little low even though it's not in the best condition but I could be wrong.
Problems:
Needs new tires
Needs a new battery
Has a cracked windshield
Rusting in places
It may have other issues but I honestly don't know what they are, if any. It seems to run fine when the battery is charged. The inside is clean. ...
