Thanks, all, for the kind words, but I think after so many years of omega ownership, the time is rapidly approaching for me to throw in the towel with them, as many others seem to be doing. As much as I adore the car it has 200+k miles and realistically is probably as nick said beyond economical repair
It's a painful conclusion to come to, but I fear you are right. I used to argue that Omegas gave me and my family cheap luxury motoring, but not so any more. Once the rust sets in, it's not cheap any more.
We got 11 Omegas at Brackley last Monday. We got 23 at High Wycombe a couple of years ago. I hope there will be another Omega meeting, but it should be soon.
I currently have 4..... and I'm very attached to NXR, more than I have been any other Omega (Apart from BN51 RUV) which took me all around spain and back without a hitch. When I MOT'd the car, it passed without a mention of anything, so I thought happy days.
A year later, it was scrapped...... on, you guessed it - terminal rust.
Not sure how it can go from no advisories, to terminal rust, in a year, but hey ho. I guess they really are getting that bad now.
I bought it off VXL V6 for a snip, because it needed a clutch. I put one in, and it literally was the most flawless, nice car you could ever ask for

and was only ever sold because I inherited something much newer
