I only use mine once or twice a month, I don't really have time to use it more often. I do thrash it every time I drive it and the car seems to respond well to such treatment. Never had a problem with it during 3.5 years of ownership.
I drive about 2000 kms per year, sometimes it is hard to justify to myself owning this car and driving it so seldom...
I try to sit in mine everyday and feel the leather, does that count..??
