FINDING ONE

Findable — a few listed nationwide most weeks. Why: 8-year production run. Estimated from build volume and production span — not a count of live listings.

THE READ

The Sightseer's backbone - eight model years, triple slides including a full-wall, and the only plan offered every year from the 2010 redesign to the end.
