OK so the audio upgrade can wait. I dropped if off for a basic service today (last year's was the biggie) and it quickly got expensive.
I had pointed out that the front discs were very lipped and my The Man had had a look. The car needed pads all round anyway and he reckoned the discs were borderline so I said to replace them.
Then, when prepping for the MOT, he found that the read ARB links/bushes were shot so that went on the list.
Finally I asked him to check out the N/S indicator fault. Turns out that the control module is glued in to the headlamp unit. So that'll be £1k for that alone.
FFS. Still, I suppose it's only the equivalent of three of four mumflies for some drone-o-box
