It's funny everyone mentioned suspension but no one really mentioned tires... Tires are your first link from road to the car and depending what type of driving you do as well as the conditions you are driving in.
I always tried to go with a good sticky summer tire for the warm weather and a good wet traction snow approved winter tire for cold ... Even though I drive 15-30 times a year in snow to the mountains etc 98% of the time in winters around here you are driving in the rain!
Sad but true on the wetcoast. So I always try to go with the best snow tire in the rain.
