...or tell me exactly what to do.
So, what I want to do(get done) is making the Flatout edition new car dealership as garage (where you can tune your ride)

The car usual spawn point could be at the nearest yellow car (don't know what slot is it). I know it's some sort of possible as I've seen that as garage in one video, but I do not remember what clip was it.
Link for the dealership
Someone could please scipt that as garage, or tell me how exactly to do that.
Appreciate it, thanks.
