Low Ballers

I was hoping I could get some advise from the members about car prices. First I appreciate what I am asking is without the benefit of actually seeing the car, but here goes.

I have a non numbers matching 1969 Dart GT convertible with 53000 original southern miles.I converted the front from SBP to BBP and disc brakes. I did an engine swap for a 1982 318, 2bbl and 904 transmission with about the same mileage. Car was originally a 6 cylinder, column shift, bench seat car. It is now a console shift (correct console) with bucket seats ( correct 69 seats). Most of the GT trim is missing (holes in trunk and doors were patched by previous owner.)

The car has a new Legendary interior, new white convertible top and deck liner, new B5 blue paint (not a great job), new brakes and lines, new tires and rims (police wheel and steel 15" BBP rims), completely rust free and detailed underneath.

So here is the thing, I am told by the "buyers" the car is worth $13-$14K Canadian Dollars.($9-$10 USD.) Does this seem right to you? I have $18,000 CDN ($13 USD) in the car. I always thought drop tops in great rust free shape were desirable cars. Thanks for your opinions.
