It is not allowed to import any (second-hand) vehicles into China since 2008. You had a great idea but a few years too late mate :/
You are still allowed to import NEW vehicle however the import tax is about the same as of the price of the vehicle itself.
Just to put things into proportion.... the 'base' 2013 997 is USD227,000 at the dealer here mate. Just visited a month ago.
It's a class on its own here brotha
