In 1984 I bought a 62 190sl from a girl who was restoring a few cars for her boyfriend, she was the mechanic, restorer etc….
She was also working on a couple other Mercedeses, one of which was a 300sl Gullwing all aluminum (one of only 29 ever made) and told me the car was worth around $250k, in those days a regular Gullwing could be bought for around $70k, the roadster for $20k less, a Dino for around $30k…
But these all aluminum ones were made for racing and many of them were wrecked in races so only a handful had survived, I guess this is one of those survivors…
