Rolls-Royce Motor Cars at 0.88 is the strongest pull in Bugatti's top 10 — but the two-peak shape signals that the neighbor set doesn't simply collapse into one tight cluster of ultra-luxury marques.
The top five neighbors are all Auto brands: Rolls-Royce Motor Cars (0.88), Maserati (0.85), Mercedes-AMG (0.82), Jaguar (social) (0.82), and Land Rover (0.82). That cluster is coherent — premium and performance Auto brands whose audiences overlap strongly with Bugatti's. Positions six through nine continue the same subcategory: Aston Martin (0.77), Bentley Motors (0.75), BMW (social) (0.75), and Land Rover USA (0.71). All nine are Auto brands.
The second peak arrives at position ten: Lamborghini at 0.68, still Auto but noticeably lower than the tight band above it. The gap between Rolls-Royce (0.88) and Lamborghini (0.68) is the structural story — the top 10 is not a uniform luxury-car bloc but two distinct tiers of Auto overlap, with the upper tier anchored by British and European grand-touring marques and the lower tier represented by a supercar brand whose audience composition diverges enough to register as a separate neighborhood.
Every neighbor in the top 10 shares Bugatti's own subcategory, making this one of the more same-kind similarity profiles in the dataset — the audience shape is defined almost entirely by the Auto category, with no cross-category intrusion until well beyond position 10.
