If we assume that when it was certified, it was as a rebodied/restoration drivetrain vehicle as indicated by the second and final certification. The professional appraisal value was 100,000-120,000 in 2008. No one on this site questioned the appraisal value then.... I don't know why, to me it was virtually worthless unless you collect documentation. So logically if it was worth what it appraised for in 2008 at 100-120K, then based on the increased value in cars 148K is not unrealistic in today market.
Again the car has very little value whether it was in 2008 or 2015. There is nothing original and should be valued at nicely restored clone cars...but that's just my opinion.
