When I bought my 54 plate DE a couple of years ago it had around 25k on it, I just acted like it was any other car I've bought an did the usual preventative maintenance as I knew by looking at the old MOTs it had done around 1k miles between some of them. Used it daily since then an apart from the exhaust rusting away an fans stopping working it's been completely fine. I do feel like I'm starting to come into the age an mileage range that the bushes are going though.
