The 560 has now been in my possession for exactly 1 year. During that time, it covered 8300 km. I've bought a total of 1290 litres of 98 octane. That makes average consumption 15,54 l/100km. This is almost exactly in line with what I get on a per-tank basis these days. "Cheap 98 octane" was 1,39 EUR / litre when I bought the thing, now it's 1,59 EUR/l.
As for total cost of ownership over the year... Let's just say it's over 50 % of the purchase price. But then, a lot of it has been spent on custom work and restoration; not just maintenance and repairs.
