The S320's are very good cars and are good for daily driving.I think the 500's and 600's are ment more for non-daily useage.But,I am sure that no problems are to be coming in my 500.Since the car does come with a warranty,even if you do run into a problem in the next 4 years,you dont need to worry about it.
