I am conflicted on the value.
Beautiful example based on the pictures. If it is a true survivor that’s a plus to the value, pristine interior, got to be worth $3-4k, no rust, good factory paint, straight panels,trim (would like to see underneath) is that worth $10-15K maybe higher with today’s paint and labor costs. Low mileage engine with working A/C….turn key. Would likely be a good deal at $18k? Maybe $24,500 is a good starting point for the seller and something in the middle as the value depending if this is somebody’s dream car.
Disclaimer : I do not know this car or the owner. Just some napkin analysis based on the description and my experience with my restoration.
