Yep can be a scary time but...
Last 3 years I have MOT'd the Zed....
2011 - 97,985 Miles
2010 - 84,004 Miles
2009 - 68,946 Miles
Work required so far zero not even an advisory, the only comment has been that my braided brake cable is possibly a little too long and should be secured
Will be scary come August this year, I should be on about 107,000 by then, can I make it 4 in a row
