Once your car has cleared customs etc, you can pick it up from the docks.. wither get it towed or get a temp reg and drive it.
You are able to take it home, i think you have to get it complied/present it to your compliancer in 100 days from the date it arrives or something like that (maybe someone can clarify that).
I know with my compliancer..... my car arrived around chrismas so he was closing for a few weeks, if my car didnt arrive in time to get it to the shop i could take it home.
