Because I drive mine also about 3k a year what is a higher 40k mile one worth these days? I friend of mine has an F40 that he drives a lot and know one ever asks what's the miles. Do you think some day it will not matter how many miles we have on our cars? and they will all be close in price regardless of miles.
Well, I drive mine too (31K mi and climbing), so I'm not impartial. When I go to a car museum, I don't look at the odometer, but I do look at the overall condition, so I tend to think that as time goes on and fewer of these are on the road the value will be determined primarily by condition and special history, rather than miles. Of course, those that get driven regularly will have more external and interior wear and tear than those that got stored in shrink-wrap, so condition tends to correlate to low miles. I also can point to a counter argument from antique and vintage motorcycles, where the "patina" of age and use is prized more than new paint and chrome. So the rule with old bikes is not to restore them to like new, but to clean them up, fix or replace broken parts only, and preserve the paint and rusty parts. But that might not be the case for our FGTs for another 4 or 5 decades, by which time all of us will be gone.
