Hey, bought a 10 plate A5 Sportback 2 weeks ago from near Audi. I know it was the dealers managers car. I received a call from an 0161 number today telling me I have a GPS tracker in my car and asked whether the dealership mentioned this. They didn't. He went on to say that demo cars are required to have a tracker fitted. He then gave me the option to have it activated for about 130 p/m. Is this suspicious in any way? Or is it legit? If legit, is it a good deal? Im assuming it brings my insurance premium down too.
