Extremely nice Piper Challenger/Archer. For those unfamiliar with the Challenger, it was only named that for one year (1973), then Piper changed it to Archer, returning to it Native American linage. The significant changes include the fuselage being 5 inches longer, mainly in the rear seat foot room, a wider wing span, the horizontal stabilizer is longer, as well as a 50 gross weight increase ......more.
