A while ago I drove my '70 280SL from Barcelona to London, in ONE session. Must have been a 15 hour drive or so, with just the 1hr car train between Belgium and Britain (it goes under the sea you know!) as a break. Otherwise, constantly between 70 and 100 mph, depending on traffic, hour after hour after hour. The car was absolutely fine, but my eyes were spinning all over the place when I finally made it home. Yes, I know it wasn't a particularly sensible thing to do...
