Just for comparison - To completly finish a '71 Cuda, lots of steel work, so it was inside and out 100% color change, with Spee (sp?) paint materials in Limelight green - the materials costs alone were $9800. That was before tax (6.35% in CT) Over $10K for the primer, sealer, base, and clear and that was 10 years ago. It is entirely possible if the guy said "I want the best" in terms of materials, and the car needs a little filler (they ALL do), setting thing gaps ,etching, primering, blocking, then finishing that $15K was not a big deal to reach.
