Did someone break in to the car?
Have you reported it to the police - they can't stop crime if they don't know where or when it's happening?
Was it parked in your garage, outside your house or in the street?
How did they gain access to the inside of the car without damaging it??
There are various things you can do to try to prevent your car (in fact any car not just a Porsche) being stolen. I'm sorry to say though if someone wants your car badly enough there is nothing you can do to stop someone lifting it onto a flatbed and driving away. And with today's traffic wardens doing this routinely, unfortunately no-one passing would even bat an eyelid.
Some of these things might prevent the opportunist thief taking your pride and joy:
1. Fit a Thatcham 1 immobilser (upstream of the battery cut-off switch) - e.g. so it has permanent 12v supply.
2. Use the battery cut-off switch and take the red key with you.
3. Buy a snap-off kit for your steering wheel and take the steering wheel with you.
4. Remove the fuel pump relay or DME relay and take it with you.
5. Don't leave an RS anywhere at all dodgy, ever - not even for a few minutes.
6. Get a very large guard dog. [
