To get the fancy dial
To be honest I never thought of it, untill I test drove a MINI with it, and was impressed by the ease of use and functionallity of it, and that was last month in the UK, not exactly the warmest place to be.
To be honest I'm probably being influenced a lot by my current transport, where I have to constantly adjust the tempreture setting to get comfortable (no air con, just a completley removable roof for the summer)
