So what is the best way to get this done on a daily driver, a four week vacation? I guess buying a spare gear set and shipping that would be better. How much total would it be to get unitrax to install the wavetrac + shipping?

I tried to get my Mercedes mechanics to take a look at my car and they didn't want to mess with it. The local chrysler stealership charged me $400.00 for things they couldn't even fix.
