I seem to be getting attracted to the 840, well more to the 850 but I'm sure the 850 is a *real* money pit.
How much care and maintenance would an 840 need? If I bought a 'decent' one with, say, about 100k or so on the clock is it something that could be kept on the road within a reasonable annual budget? Or, is it a real enthusiast's car needing frequent tinkering and costing £1500 plus per year just to keep it up to scratch without even thinking about using it?
