FINDING ONE

Patient search: weeks of watching, and probably some travel. Why: only one model year; still in production. Estimated from build volume and production span, not a count of live listings.

OUR TAKE

Dry weight published as 'approximately 43,500 lbs' rather than an exact figure — confidence downgraded to med. No model-specific price published, only the line's $922,040 starting price. Collected from a census gap: this line had no catalogue record at all. tier, bn and mat are the collecting pass's editorial read, not inherited from siblings. Slide-out count added by a later pass: spec table row 'No. of Slides' / '3' seen in raw HTML
