For many reasons, including the high cost of product liability insurance and dwindling production volume, the price of new singles pulled ahead of general inflation. Because airplanes have always been expensive, price increases of several percent or more per year compounded into substantial dollar volume price increases. For example, according to Vref, a leading value reference of existing airplanes, a Bonanza A36 had an average new price of $330,000 in 1990. By the year 2000 the price for an A36 was up to $530,000. And if you step back 10 more years the A36 new price in 1980 was around $139,000.
