If you look at the auction houses, prices are always higher. Just one year ago, a mid-mileage GT could be bought for $250K in a private party purchase. Although prices have been moving up for maybe two years, the greatest rise has been most recently—the so-called “hockey-stick” curve. Which is what makes me think we are in the overshoot region of the graph of market price movements. Which is why I would not be a buyer at current prices. I’d wait for the market to stabilize again.
Just speculation though. I don’t have a crystal ball! And I'm not selling mine anytime soon.
