I've been attending collector car auctions for about 30 years (not as long as a lot of you I know...) and for maybe 25 of those years I walked away thinking "people are crazy, always over paying".
The it occurred to me that maybe I was looking at things incorrectly. How was it that I was right about prices (they were always too high) and all of those buyers were wrong?
The market is what it is. If after a long time period you think everything you look at is overpriced, it may be time to adjust your thinking.
If you are looking at spending $250k on a car just because you like it, you likely can afford another $20k. Just spend the money and don't look back.
I use it to motivate myself to earn a little more. I figure I can always make a little more money!
Just find one you like and buy it.
