These are NOT the highly sought after manual seats - that if in excellent shape/recovered sell for $3k - maybe slightly more. I'd say (unfortunately) anyone that got these seats for free and pays the $2500 or whatever to recover them in full leather will be upside down.
These seats below from this ad are in pretty decent shape
