Gotta love this SS/GA Dart

Any idea what it cost to put one together like that? It would be nice to see more detailed pics of the car like the underside and the rear tube. A 68 DQ 440 Dart may be my next build as i have 90% of what i need so details would be nice.

Having built a car similar to it, I would say it would take $75k at least, just an educated guess.
