Same here, I've got a company car so over winter I never bother using the Z. TBH I barely use the Z anymore, its too much of a hassle getting it out over the speed bumps & its too loud to talk to passengers or drive for extended periods.
As for why I do it, its a hobby - I don't have many hobbies so this keeps me entertained & I've made a lot of great friends through this place. If I had to drive that sh1tty red van every day of my life I would kill myself
