V12 W140: true running costs
Hello to all! I've admired the W140 chassis for some time, and finally it's time to give them some serious consideration.
I've owned a 1989 1/2 Jaguar XJS - while not exactly cheap to run, it is feasible to use as a daily driver, as the weak points on this vehicle are well documented. As long as you stay ahead of the curve on the repairs, no problem. Also nowhere near $10k per year for upkeep.
Scouring the internet, I find that $10k per year for upkeep on a V12 W140 Mercedes sounds like a rather steep figure. After all, these were the flagship, and as I understand it are quite reliable.
What I haven't seen is any discussion (other than the timing chain) of known weak points. I understand that low production #s and the owners financial ability to make repairs as necessary probably keep a lot of talk out of internet fora, but if anyone could shed some light on what to look for, and what your experiences have been, I would appreciate it.
I'm most interested in the 1992 to 1997 range.
