* Condition: A concours-quality, completely original, documented example will be worth significantly more than a car needing restoration or with modifications. Rust, wear, and tear all impact value.
* Documentation: Factory build sheets, original paperwork, and service records dramatically increase value. A car with a verifiable history is worth far more than an undocumented one.
* Modifications: While some modifications might be desirable to certain buyers, others might decrease value. Any deviation from original specifications needs to be considered.
* Mileage: Low original mileage is always a premium.
* Specific Options: Certain options were more desirable than others when the car was new, and this affects collector value today.
* Market conditions: The collector car market fluctuates. What a car was worth last year may not be what it's worth this year.
Because Petty-built Road Runners weren't produced in the same volume as Yenko Camaros (and were far less formally documented as a production program), establishing a price requires expert appraisal. You wouldn't find a readily available "blue book" value.
To get a realistic appraisal, you would need to:
1. Consult with experienced muscle car appraisers: These specialists know the market and the nuances of these rare cars.
2. Contact major auction houses: Review auction results for similar Petty Road Runners sold recently. (Note: this gives a *range* of values, not a precise one.)
3. Check online collector car resources: Sites specializing in classic car valuations can provide estimates, though they won't be as precise as a professional appraisal.
In short, while you can find general ranges for similar-era Road Runners, pinpointing the value of a specific Petty-built 1972 model requires professional expertise given the rarity and variation among such cars. Expect a value significantly higher than a typical 1972 Road Runner, but a precise number is only obtainable through professional appraisal.
