Rob, you are absolutely right about the value in something like those cmp mirrors.
At the risk of offending anyone / everyone, it always astounds me at how cheap Canadian mv enthusiasts are.
I've seen guys spend hours and hours fixing something, which is available NOS but "too expensive" rather than pry open their wallet. How much is your time worth? Figure the average wage at $20 / hour, spend a day fixing a piece of junk, and hmm, that $50 part doesn't really seem bad afterall...
I have been around fellows that collect everything mechanical, from lawnmowers to tanks. Look at guys who restore old cars and see the lengths and expenses that they will go to for that special part. Anyone priced out a fender for a '57 Chev lately? I'll guarantee that if you can find a NOS one that you're in the neighbourhood of $1000USD. Rear fender NOS M37 < $75
As far as I'm concerned, considering the historical signifigance as well as the age of many vehicles out there, by far the mv hobby is truly a hidden secret when it comes to economy and value.
Thanks Rob, you got me going... I'll get off my soapbox now.
