I believe Preventative maintenance is better than cure. As I put my life in its 130mph hands a lot I do something on it most weekends, and have a little check over things. I do appreciate not everything can be guaranteed until its too late, I also have breakdown cover just incase I'm miles from home. I carry my work tools most of the time anyway, and many a time a bolt/nut/tie wrap/pair of grips/other parts from botttom of tool bag have got me out the sh!t! I'd hate to wait for a tow truck if it was something so simple to fix but I wasn't prepared...!
