The guys who tried to steal my car were well dressed in broad daylight . They walked onto a guarded parking lot . One even waved at the guard . I just happened to be walking to my car because I had forgotten something at home . It was 10 AM that day. From a distance I thought it was a kid . When I got closer it wasn't . He was a 25 year old but I was 35 back then and in shape too . It scared the crap out of him and he ran from my car into a getaway car . I was standing right in front of that getaway car . They almost ran me over . They had no tags at all on it .
My point is that Porsche theft usually is a pro . I think they will find your hidden tags in a dumpster somewhere . Besides if you get the car back its likely damaged, stripped or destroyed.
