I drive mine when ever I want but park it during the winter. I've had it since september of 2009 and I only have about 13,500 miles on it. So I'm averaging about 4,000 miles a year give or take. So I don't think your that bad. I'd say I'm on the really low end but there are a lot of us that don't want to expose our cars to the salt they use on the roads here.
Hell Joe's had his car for a few months longer than I have and I don't think he's hit 900 miles yet!
