After reading the list I gulped for you and shook my head Bigron.
However, after reading the comments from those who know I think it is worth the expense (if the funds are available) and effort to put everything right. Your Omega is worth saving, as what are the costs for buying anything equal to it?
Mine had "advisories" with the MOT of two years ago faulting corroded front brake pipes. After gaining advice on here I got underneath the car, cleaned ALL the pipes for their entire lengths, sprayed with a protective coat of Supertrol everywhere, and I even attended to some small areas of rust on the underside (not faulted though).
With the last MOT, at the Vx dealership I use not the one that had given me the previous advisories, it sailed through with no advisories!
So I reckon Ron get the wire brush and Supertrol, or similar, out get underneath the whole car and go from front to back cleaning and protecting. Take up the advise of other to get the other jobs done (Serek is certainly my highly recommended choice after he d id my front wishbones, plus a lot more) and get the car MOT'd at a different garage that preferably know you and your car
SORRY RON, JUST SEEN YOUR LAST POST!!! NO, YOU CANNOT DRIVE WITH THOSE EYES CONDITIONS.
Have you got any friends or family who can drive the car to a local garage?
