I don't think the mileage matters, if you fancy a flash car and can afford it just have one, why deny yourself?
I knew a bloke who had a DB5, drove it a handful of times a year and then not very far. I asked him once why he didn't just sell it and he looked at me like I was insane. Just owning it gave him pleasure. It was the proper Bond one as well, in the gun metal grey.
