Not done before because it's not really needed? Changed 1 idler on one Omega out of 4 over the years. Never touched 3.2's either....
Across both of mine never had advisory for one either, combined miles from me of arouns 150k. That's before you factor in the other 2 we had for ages.
I think some people only change them when they can't get an MOT. The sort of driver who wants tyres that are cheap, round and black. Having driven your old beloved 2.2, as well as been in the car with you a few times, your driving style most of the time fits into that. TBH, with your 2.2 suspension/steering whenever I drove it, I think it would be hard to feel from the wheel that the lack of precision was the idler or not.
Some people like their cars far more precise and predictable - it was blatantly obvious om my beloved silver bullet when idler gained some play.
So, if you fall into the latter, this
might be a viable alternative to GM
