It's on 56k now. Was low high 20s or low 30 think when I got it (other z4 was the same). So it has crossed my mind again now I'm getting near 60k. I have seen an odd one or two on the forums over the years. But normally they are not a clean looking example. Plus you just don't know how they or its previous owners drive them. I will be looking into it much more next year though. As like you said I plan on keeping it as I certainly can't afford anything better after getting the house.
