You also need to watch the information about the Porsche 911, starts about 29 minutes in. I won't spoil the surprise.
This video is dated April 2019, what did they do with this, or what do they do with these kind of cars in general? Parts? Restore? Sell?
I admit to being curious, so I went out to their website. They do not appear to do the restoration work (they have a post about a "barn find" 911T. They show the car coming out of the storage garage, and then a huge number of photos of the finished product.
They do have some rather nice vehicles on the Sales page.
I could find no further reference to the 280 SL and what happened to it.
