Well the first two are definitely made of unobtainium now!…not so much the 916, it really is the ugly duckling of their history. Funny how people have become fond of it again. Like the 924, for whatever reason it’s found it’s audience finally…
As for the why, why do any of us put value against any of this stuff? It’s definitely not rational.
If it were we would be having this conversation over at the RC200h forum.
For me the 928 was always a hero car. I was in my teens in the early nineties when this car was king of the hill. I used to read my dads hand-me-down Car and Performance Car and I just loved the look of it. It also won Top Trumps as it was, for a long time, the most powerful normally aspirated v8 of any production car. Which was quite a bragging right.
Then there was Risky Business and Weird Science.
Finally my dads best mate had one. My dad had a mondeo at the time. This was like a spaceship!
