Don't forget to contact the Social Security Administration and have a new SSN issued to you. Then get on the phone with the credit reporting agencies and make sure they're aware that your SSN has been stolen and that as soon as you have a new SSN you'll inform them. It may also be worthwhile informing the DMV too.
The credit card companies may catch them when they try to use the credit cards but if they're career criminals, no action may be taken till a large enough case can be brought against them.
As for your Z, park it somewhere else till you can change out the locks and ignition.
Good thing you're still alive.
"The 300ZX Turbo is a dance; it's a song; it's rolling, roaring automotive art. There is no color that doesn't suit it. There is no mood-lifting chemical substance it can't replace." - Automobile Magazine
