Wow, I didn't realize these model had so much value.
The cost for a paid-for restoration from one the major shops varies greatly, but always seems to in the $90k-140k range.
Its a pleasant delight to see classic Bronco's keep increasing in value and collectability. I'm always open for new and interesting investments.
Classic Piper airplanes did the same thing. I used to buy em' for $30 - 50k, the last one I sold for $93k and gave the buyer a great deal!
