FINDING ONE

Patient search: weeks of watching, and probably some travel. Why: an uncommon body style. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

The one to buy if you want a separate lounge: a real dinette behind the driver plus rear twins, so nobody has to break down the bed to eat.
