C207 E Coupe 350cdi, W166 ML 250 Cdi Sport, R171 SLK 350, Suzuki V Strom DL650
It is gorgeous, but 28k miles in 25+ years, it will still need lots of components changing, as rubber will have perished over time.
My feeling is that these cars need to be driven, and once this one is driven a little more regularly, it will not be that reliable without money being spent.
The sub 30K miles is not the be all & end all imo. Anyway, for that wonga I'd want a 560, a different colour, velour upholstery too along with deleted mud flaps (I think they look awful) and a drop in ride height. Still, that sure looks like a very nice motor. Good luck to the new owner.
