No I don't mean public sector pensions. I'm wondering if there are any parts so likely to go that it's worth changing them before they do. I always change the battery before it's time because if it goes you're off the road and maybe left stranded. In the past I've twice had an Accord driveshaft boot split on me when the car reached 9 or ten years old. & 7th Generation seems heavy on anti roll bar droplinks. If you want to DIY on the driveway better done in the spring and summer as winter is too cold for that malarkey. Or is doing this sort of thing just wasting money & better to say if it ain't broke don't fix it?
