Zero things have gone wrong with my 2001 S430.
Extremely pleased with the 2001 Mercedes-Benz S430 long wheelbase. Exceptionally quiet, roomy, well-appointed, and very spirited performance. Fuel economy superb, for such a large car (26 mpg, combined city/highway).
Beautiful interior. Very bright, flowing, organic forms, throughout. Leather seats and alcantara trim throughout are exquisite, and the calyptus wood accents are very tasteful.
I could not get the car to misbehave, even in the slightest, on snow or glare ice, and this car is only 2 wheel-drive. The stability program works amazingly well.
I am 6'4" tall, so driver leg-room and headroom are crucial. I could adjust the driver's seat so that my feet could not reach the brake or accelerator pedals, which was something I could not do in any other vehicle that I tested. Seats were very firm - the way I like them -- less fatiguing - and very comfortable, regardless of trip duration.
The integrated COMAND GPS/audio system was not all that difficult for me to master, and it functioned flawlessly. I ordered the dealer-option trunk-mounted 5 CD changer, and it functioned perfectly, too. The Bose premium stereo system is phenomenal.
The 4.3 liter (260 cu. in.) V8 engine is superb, and provides more than adequate thrust off the line, and for passing at highway speeds, as well. Dead-quiet at idle, but gorgeous, subdued V-8 "burble" and "growl" sounds, when it got up and talked. Bear in mind, this is only the S430. Its bigger brother, the S500 (5.0 liter V8, 302 cu. in.) gives more performance, but at considerably more cost - about $8,900 USD more, for only 27 more horsepower, so the overall driving experience is more a difference in degree, rather than kind. The S430 is really the "sweet-spot", in terms of overall performance/value.
I considered the 2001 BMW 745il, but to my eye, the overall "curb-appeal" was lacking, particularly since this body style was essentially unchanged since 1996, so it was rather stale (the 2002 BMW 7-class would not be out for another year, and as it turned out, the styling to me was very jarring and disjointed, particularly with the rear-end treatments.)
An all-around beautiful car, and a wonderful driving experience.
I for one totally agree with this forum. I just purchased a 2000 Mercedes S430. It has no problem keeping up with the S500 and S600 in terms of performance, luxury, and appearance.
My previous car was a 1994 Mercedes S600. It had a V12 with almost 400 horsepower. It was very uncomparable to my S430 in terms of performance. 0-60 felt like it took forever and do not attempt any slalom tests or psychotic trans-lanes highway driving. You will probably get a total loss of control over the 5000 lb car.
Also my S600 was oversized, overweighted, and the exterior and interior design was very square and rectangular. The long-wheelbase sedan was impossible to park anywhere. At least with the S430, you get some more space to park.
The S430 did come short of options like headlight cleaners, xenon headlamps, power rear seats, heated front and rear seats, power rear sunshade, and parktronic parking assistance (which were all standard on the previous S600). Also, at least this car is about 1500 lbs lighter and gets much greater fuel economy.
I had one and it was a lemon. Electronics worse than the reputation of Jaguars.
