I'm in exactly the same boat.
Just about to retire the City jacket in orange, which I've had since 2012, I think.
I'm thinking of the hooded rain jacket as well, but £230 is steep. However maybe I don't mind spending decent money on a jacket if I'm going to get 7 years out of it.
I see Vulpine still do their Harrington, but I'm wary of it as god knows who's making them now and I can't see one IRL to gauge quality.
