That could even be on the high side, it depends on the model and body style. If it's a touring or roadster, that's a steal. But the 4-cyl coach and sedans are only $9000 and $7200 for mint cars, the 6-cyl a little more at $12,000 either way, according to the book I am looking at. Books are guides, though - I think $6000 is reasonable for a running, driving 20's car - especially if it's all original or well cared for all this time.
