Well, what can I say, took the Omega in for its MOT this morning and to my surprise, it passed.
Did get an advisory for both front tyres, which I was expecting, and a small bit of rust on the rear of the d/s sill. But when you consider that the car is 18 years old and never had any welding work, I think she has done quite well.
Only paid £200 for her 3 years ago and she has passed her MOT every year with no issues to talk about and now has over 150000 miles under her belt.
Don't think I have any grounds to complain.
