If they were close to me I'd be interested in a good set of fronts only, for cheap.
Rears and 3rds, not so much.
Craigslist is my go to, and free.
lots of other folks using FB marketplace I guess if you're in that thing.
It depends on where you are.
Bigger cruiserhead market = more possible $
In the boonies? Good luck.
Maybe someone would pay shipping if they were cheap enough.
Around here the 3rd rows are negative value as nobody wants them and many people give them away rather than store them and never, ever...
