two weeks ago and after a bit of more than 8 years I clocked the 200,000 kms on my E63 S211 AMG. Just wanted to share some experiences and a warning to you guys (just be aware, that I drive the car a bit different here on the Autobahn, so I guess the stress in Oz is not that extreme): To summarise it: It is still the second-best and most unreasonable decision of my life!

Pros and Cons:
Very reliable, main repairs were a rear diff @ 80,000, the motor hood cable got stuck once, and one cat had to be replaced. I had a noise from the servo pump which required a replacement. All the electronics incl. dynamic & electric seats, command, telephone, linguatronic, etc. etc. worked fine, no probs.
An oil analysis at 180,000 kms turned out to be perfect, hardly any particles.
Oil consumption was constant from the beginning; between 0.2 and 0.25 litres / 1,000km. Fuel consumption was between 10.2 and 23 litres with an average of 16.3 litres overall. Not bad for a 2-ton-station-wagon driven at the limit most of the times.
Surprisingly, brake discs at the front were only changed every 50,000kms, at the rear at 150,000kms (some people have them done at 20,000kms). Typres at the back around 20,000 kms (which is good too, as there are specialists acc. to my dealer who need some every 7,000kms).
Cost: Driving an AMG (or a 6.3 or a 6.9 ...) is just expensive. As a private person I wouldn't drive that car. ONE front brake disc is already over 800 Euros. Total cost of all inspections and repairs: 25,700 Euros, Tyres 10,500 Euros.
Summary: It's absolutely fun, but VERY expensive. Don't buy a used one with a small budget, it eats you up. I took really care of the car, never used the power until the oil was properly heated up etc. etc.
With my best regards
Thomas
