First of all, weren't the keys locked up?
This is a fear of mine also. I have a limousine service in Ohio with 16 limos, hummer limos, escalade limos, navigators, chrysler 300s, party buses etc etc I pay big bucks to store them all inside and recorded by security cameras that can be monitored at home over the internet and this is a major reason why. Also I read countless stories about companies from all over the country that have catalytic converters stolen from under the car while parked outside, spare tires stolen, cars on blocks, etc etc.
I wish ringgold the best of luck. Let there be some good in this: lesson to all viper owners, park your car inside your garage at all times. If you dont have a garage, get one, or rent one ASAP.
