I'm thinking about selling my '72 /6 Scamp. I'm wondering what the car is worth. I'd appreciate you thoughts.

1972 Plymouth Scamp, 225 slant 6, automatic, 45,000 original miles. Runs, drives, and stops great.

Modifications:
Repainted exterior in 2014 - mediumm green metalic
Numbers matching car with build sheet and VIN tag
Stripped vinyl top, top painted black
Small bolt pattern wheels painted body color with Plymouth dish caps
Second set of black wheels also come with car
Disk brake conversation from 1968 Barracuda with new master cylinder
Water separator installed
All new brake lines
New gas tank
New front and rear bumpers
New front spoiler
Original radio works and has been converted to have aux and Bluetooth inputs
New front under-dash speaker

All gauges operate correctly

$8-12K IMO. nice 318s are going in the $13-25K range
