Driver buy a new car from showroom but how he reach home?

well i think you would want to bring someone with you if you have a trade in it workes on most cars but if you go bye it don't have a trade in you could drive it home unless you didn't live where you got the car then you would need to have it transported to your home but if you have license you could drive it if you werent using the car you have as a trade in you would need to take someone with you so the new car could be driven and the other car be driven to your home
