Sent the mk2 into my local mechanic today to get the ingnition switch replaced, went to collect it after work with carrie, drove both cars back to my mums house and she mentioned that the steering wheel was a bit "wobbly!".
So I investigated further, and much to my horror, the steering wheel came off

After a little more investigation it became apparent that the mechanic had decided not to refit the nut that holds it in place.
Am just glad that it held on till we got to my mums, as it could have been very nasty indeed.
