Sixt - GPS tracking on Sixt cars?

Do you guys know if any rental agencies in Europe have GPS devices hidden in their cars to track them? Just wondering...

Back in the late 90's Europcar had stickers in some cars indicating that they were tracked. I did see a few of them myself when I was working for Europcar, Sweden. All the cars I did see with these stickers were on german plates.

We had a huge problem with rental cars disapperaring to the east in those days. Guess that's far better now.

Haven't seen these stickes for years now, even on Audi A8's, Mercedes S-classes etc.

Or what if they're not warning you anymore?

I don't know what the EU laws are, but I have rented numerous cars from Sixt, Europcar, Hertz, Avis, Budget, and more for the past five years - and none of them ever had warning stickers. Yes, even Obereluxus - Benz S320CDI, BMW 740d, etc.

Maybe in the past they did, but not anymore. You can always try asking. :) Are you planning on taking the car to Russia?

I wonder if they use onboard GPS to see where you go or find the car (must have a cell phone to dail out).
