Truly a thing of Beauty Gwilym....
I spent many happy years driving Sennies ( & a Monza....) of All revisions
you want to deal with the beginnings of Rust on the rear arch/door inner seam... sooner rather than later....
the Omega's okay, but it's not really in the same league for Solidity or Reliability, or IMHO the extreme end of the handling envelope, the senator was always very assured and progressive, and stable.....
i did something like 750,000 miles in them....
But I have to admit, I prefer the analogue Dash..... the Digital ones always looked tacky to me, and of course in some lighting conditions........ much harder to see.
also, watch out for Fusebox overloading , you need to visually check it regularly..... signs of trouble are any darkening of fuse bodies, and distortion of the fusebox contact mounting block.... it's fairly common ..... Fan speed Switch being also a common failure... and in some cases the two are related... as the fan controller starts drawing excess current as it's contacts carbonise... it'sa bit of a bugger to get at and clean or change.. but it's a good idea to do so...
also the main headlight switch... goes "dicky" with age and starts needing replacement or re-building every so often....
I've toyed with the idea of getting one and restoring it to showroom condition... but with 3 cars already.... the drive way is crowded enough... and the Garage is used for other purposes...
so I just go a bit misty eyed and wistful over them instead.......
(if they had done a senator estate as a production model, I might well have still been driving one ! )
enjoy it.... they're lovely.
