I have owned a 1999 C43 for 10 years, have 94,000 miles on it.
I had a 1992 Porsche-built MB 500 E before that.
I have owned many very high performance cars (1973 Datsun 240Z re-manufactured into a Scarab, 1954 Austin Healy with a 350 Chevy etc. and this one is my favorite. It is a a comfortable, reliable, solid, fast, functional sleeper. It is known locally as my truck, since I use it mostly to haul building materials of all sort. I love this car. My wife has a 1997 E550 and it is good, but not C43 good.
The exhaust note, the acceleration, the instant braking and the handling.
