I had a 66 Hemi Charger, Gold, blk int, 727, 36k miles. Bought it at a Collector car auction in Oklahoma City at 9:30 am for 3500, as only one other bidder spoke up and it was no reserve. He went away after I raised his opening bid by $1000. It had a 440 in it but still had Hemi emblems on the fenders and a correct Hemi VIN. I brought it home and bought a complete 66 426 Hemi core engine, rebuilt it and after it was all put together, it was a beautiful car. Had the trim re anodized, resprayed it factory 66 gold, the original blk interior was mint.
That was the hardest car to sell I ever owned. It took forever and the market was hot. Everyone loved it, but not enough to put out more than 30k and I finally sold it for 28K just to move on to other projects. This was 15 years ago.
If I bought another one, it would definitely be to keep and not plan on ever selling it.
