I believe the Subaru Legacy BP5 has a strong influence and fan base worldwide.
Although it may appear relatively ordinary in stock form, its popularity and cultural impact—especially among JDM enthusiasts—are undeniable.
With Forza Horizon 6 reportedly set in Japan, I think the Legacy BP5 would be a very fitting addition to the car list. The car has exceptional potential for modification, and once tuned, its performance, stance, and visual presence are truly outstanding.
I also noticed that previous Forza Horizon titles have already included the Subaru Legacy B4 sedan, which means the base model and assets may already exist. Based on this, adding the wagon (BP5) version should be relatively straightforward.
If you consider and apply this suggestion, I would like to sincerely thank you on behalf of the entire BP5 Legacy fan community.
