Well, I do tend to add miles :-) done 5,000 miles in 6 weeks in the Tesla so far.
I will have to check the S4 mileage when I next get over to Richard Thorne's as it is in having some winter fettling ahead of the next MOT.
The last service I had was the 70k one I think.
Mind you, all the suspension, wheel hubs, brake discs, steering rack etc is all quite new, probably less than 5,000 miles since being done. Brake discs have been done 2 or 3 times from memory. I have a massive amount of paperwork on all the bits.
