Well, it was a several weeks ago and I've largely let it go. But I did only post on here just in case anyone else was thinking of selling their car to someone in Colorado.

After I confronted him, he did tell me that he was not selling any of the parts that I specifically offered for sale with the car itself (bodywork etc). And to his credit, they've not shown up on eBay. We just don't see eye-to-eye on this

In his mind he gave me a fair price for everything he got. In my mind I gave him everything that I agreed to and (after his repeated request) I gave him a lot of stuff that I did not initially offer - for free - which he intended to sell for his own profit. I've got no ill-will over the car, I'm just a bit pissed that he convinced me to give him all those other parts so he could make a tidy profit on the "deal"

Anyway. Water under the bridge. Lesson learned. I got careless because vintage volvo people are by and large such great people to know.
