How do you treat your cars??

Is it driven everyday as a workhorse and just generally maintained or is it pampered to a carpeted and heated garage and only brought out if it's guarenteed not to rain??

You see, the fiesta is starting to do my tits in so I may be on the hunt for another ERST. I was just wondering if one would stand up to a 50 mile round trip to work everyday and then being used at nighttime???
