Lesh owns a 1979 Piper PA-32RT 300. Lol, also known as a Lance II. Anyways, one of those runs from about $80,000 - $130,000.
But airplanes in general, like an older Cessna 172 and a slew of airplanes like it can run anywhere from like $20,000 - $60,000.
You can find stuff for less then those prices I posted, or drastically more. All depends on the airplane man.
