I got to around 15k on the stock continentals......but I drive a little aggressive.

As a sidenote.....I go to Oakville and Brampton a couple times a month......I always try to go into Toronto...........I love the stares I get in my Crossfire. If you get one you'll love being the center of attention in the middle of a bunch of Beemers. I almost think the Toronto has a law that every house has to have one BMW.
