I am looking into buying a 2009 SX4 AWD (AT). I was looking for some of the bells and whistles (i.e. AWD, power locks, etc) and thought the mid-level SX4 suited me fine. I have noticed the higher end model comes with ESP (electronic stability program). I haven't had much experience with this as this is only my second car but is this worth the extra expense (I live in Canada and it does get quite snowy at times). Thanks!
