I heard a story about an Audi Dealership a while back.
The guy dropped his RS4 for service before he went away on holiday for 2 weeks.
He came back from Holiday and walked straight in a demanded to see the service amnager and asked wether his car had been driven at all. The manager said yes after the service the car is driven to make sure all is ok.
Anyway the guy then asked why is car had been speeding and being driven at night and during the speed breaking the speed limit. Manager looked at him blankley. After a brief chat it became apparent that the guys owned a tracking company using GPS and had been tracking his car from Spain.
Audi UK denied to coment on this story when it hit the press
