Data points on 700 sales are few and far between. NADA lists a low retail of $7.9k, an average retail of $15.2k, and a high retail of $24k (see the link below and notes) - - - but doesn't distinguish between a standard vs. sport coupe.
Any thoughts on current market values?

This vehicle would be in mechanically functional condition, needing only minor reconditioning. The exterior paint, trim and interior would show normal wear, needing only minor reconditioning. May also be a deteriorated restoration or a very poor amateur restoration. Mostly usable “as-is”. This column does not represent a “parts car”. Note: Some of the vehicles in this publication could be considered “Daily Drivers” and are not valued as a classic vehicle. When determining a value for a daily driver, it is recommended that the subscriber use the low retail value. Average Retail Value

This vehicle would be in excellent condition overall. It could be a completely restored or an extremely well-maintained original vehicle showing very minimal wear. The exterior paint, trim and mechanics are not in need of reconditioning. The interior would be in excellent condition. Some vehicles may be considered “matching numbers” vehicles.
