The top 10 neighbors for Mack Trucks span nine distinct subcategories — no single kind dominates, and no other Car Maker appears anywhere in the set. That breadth is the defining structural fact of this audience.
The shape is broad, with scores running from 0.71 down to 0.65 across the top 10 and no single neighbor pulling far ahead of the rest. Storage Rentals of America (SROA) leads at 0.71, the only Moving and Storage entry in the group. Behind it sits Keystone Automotive (0.67), a Parts and Accessories brand and the only automotive neighbor in the top 10. Then comes Cleveland Cavaliers (0.67), Aldi USA (0.66), and James Harrison (0.66) — a Sports Team, a Grocery and Superstore, and an Athlete, in that order. Game X Change (0.66, Hobbies Gifts and Crafts retail), Troy Polamalu (0.65, Athlete), Tim Hortons (0.65, QSR), Cardale Jones (0.65, Athlete), and Home Outlet (0.65, Home Improvement and Hardware) round out the ten. Athletes account for three of the ten neighbors — the largest single subcategory — but even that cluster is spread across football players with no unifying brand context. The cross-kind pattern here is pronounced: a truck manufacturer's nearest audiences look like grocery shoppers, sports fans, QSR customers, and hobby retailers, not other vehicle brands.
This wide, category-diverse neighbor set points to an audience defined less by automotive interest than by a broad Midwestern, working-class consumer profile that overlaps with many everyday-spend categories simultaneously.
