A few suggestions

The ability to buy/sell/gift barn find cars: Some people don’t want some of the barn find cars at all, and I, and I assume some others, want secondary copies of barn find cars so we can have a tuned and stock version of it. This was allowed in FH4, why not in FH5.

A MUCH LARGER garage capacity: Some people love having a sizeable collection, and as far as I know, 1000 is the current cap.

Organise by custom categories: The ability to organise our cars into custom categories, or have a labelling system so I can sort between cars for racing, drifting, etc.

I’ll come up with more as they come to mind.

You were able to have groups set up in your garage back in FM4. That’s one feature I really miss.
