Our 2 prime ministers Trudeau had the family 300SL roadster in the same shop as my Austin-Healey, and an alloy Gullwing was in the same shop when my Healey was there for her restoration. It sure didn't look like the $4.2 million it sold for.
My personal preference would be a roadster, since a lot more user friendly. I have both in 1/18 scale so will be quite happy to look at them in my display case whenever I want to, without having to sell my home to afford the real thing. The thing that gets me with these atmospherically priced vehicles is how much you can obtain for a fraction of the cost, and mine are all in great or restored condition. My fleet of 6 collector cars are probably worth only 10% of what this will sell for. I feel fortunate but I am in comparison just a mere mortal!
