A new Piper single-engine turboprop costs between $2.5m for a 2023 Piper M500, and $3.5m for a Piper M600/SLS (according to Aircraft Bluebook’s Spring 2023 data). Buyers can buy a used Piper turboprop for less, with the price ultimately depending on the model, age and condition of the aircraft. For example, Aircraft Bluebook’s Spring 2023 data shows that a 2010-model Piper Meridian retails for an average of $1.12m, while a 2001-model Piper Meridian costs $600k. A much older 1980-model Piper Cheyenne costs $360k.
