The Mercury Marauder was not aimed at women.Last time a manufacturer decided to have a brand focus on women was Mercury and we all know how that ended.
I never thought of Mercury as being aimed at women.
I think Buick should be the Safety and Reliability brand. If men want that then no one is excluding them. Or the transgendered or anyone else. I am not advocating Buick only offer vehicles in shades of pink. For many years Volvo was the safety brand. Toyota is mainly the reliability brand. Even as it offers TRD vehicles and two sports cars.
GMC is the offroady luxury truck brand.
Chevy is the mainstream brand.
Cadillac is the performance and luxury brand. If Cadillac is going to sell cars in the $150k-$450k range then I would push them up market too. The average new vehicle cost $48k. Maybe start Cadillac at $50k-$55k.
