Saw this Friday and watched it through the weekend right up until the auction ended. Was hard resisting the temptation to put a bid on it myself as the seller is just 40 miles up the road, but I managed to keep my finger off the bid button. Still can't believe it went for just $500 considering less than 470 of the 110 PE's were ever built.
