Kenn,
The 1951 Frazer is a very rare beast. They only manufactured 152 Hardtops and 131 Convertibles according to the book; "The Last Onslaught on Detroit" ref page 124. As in all old cars condition is the major factor, $3,000 seems to be the average non drivable price for a car that can be restored. Upwards of $13,000 is a fair price for a restored, drivable car. However, having just restored a 54 Kaiser I have much more than $60,000 invested and I wouldn't sell it of anything less than $100,000. So it is all in the eyes of the owner and buyer. As they say they don't make them anymore! One other factor is parts availability, many of the trim and sheet-metal parts are not available at any price!
