Arnold Motor Supply's closest audience match is Fareway Stores, a general grocery chain, at 0.91 — not another auto parts retailer in the top 10.
The shape here is broad: eight of the ten closest neighbors score above 0.80, and no single entity dominates. Fareway Stores (0.91) leads, followed by Brown's Shoe Fit Co. (0.87), Best One Tire & Service (0.87), Hy-Vee Pharmacy (0.86), and Runza (0.85). By subcategory, the top 10 break down as: three Convenience Stores (Casey's General Stores, Hy-Vee Fast & Fresh, and one Gas Station), two General Grocery Stores, one Footwear retailer, one Maintenance and Repair Services, one Pharmacies and Drugstores, one QSR, and one Home Goods and Furnishings. That is a strongly cross-kind cluster: Arnold Motor Supply's own subcategory — Parts and Accessories — does not appear among the top 10 neighbors at all. The audience shape is defined almost entirely by everyday-errand retail: grocery, convenience, fuel, and pharmacy. Best One Tire & Service is the lone automotive neighbor, and it falls under Maintenance and Repair Services rather than Parts and Accessories. The remaining neighbors — Rent One (0.82), Casey's General Stores (0.81), Hy-Vee Fast & Fresh (0.81), and Hy-Vee Gas Station (0.81) — reinforce that pattern, as does Hy-Vee itself at 0.80.
The overall picture is an audience shaped by Midwestern, community-anchored daily commerce rather than by automotive specialty retail.
