I'm a bit surprised with that 1, nice build but more of a resto-mod. A lot of the cars that have been hitting bigger money have been original examples. But yes another sign.
I can't help but think there is a bit of a shift in the collector car community, away from exotics that are a fortune to maintain and require specialist care, more toward simple, tractable, reliable cars that can be enjoyed whenever the mood is right.
Basically cars that can be easily maintained by the home mechanic without sophisticated tools or diagnostic equipment and are easy to work on. This may explain why early Air Cooled Porsche's are doing well, along with the Japanese stuff which in many cases is easy to tinker with but also dead set reliable..
