I'm sorry John but I disagree. Lexus have as many (if not more) electrical gadgets as standard but they still do well in consumer surveys.
It seems Mercedes are slowly getting better, it's just a shame it was allowed to get so bad during the mid/late 90s.
Imagine telling the bloke that was building my W124 in 1994 that in ten years time Mercedes' apalling reputation for rust would force them to try and improve their rustproofing to Fiat's current standard.
Well I think John is right. Consider what JD Power say about Lexus: -
"The Lexus IS is second in class and third overall.
Owners reported very good interior build quality, loved the way the car drives and looks, and rated Lexus dealers as among the best.
There are chinks in its armour, though. Mechanical reliability was only average; a number of owners reported engine faults. Running costs were so-so, with relatively steep fuel bills."
I sat in a friend's Skoda. the drivers seat is simple and adjusts purely mechanically. Like an old E class from the 80's. Nothing wrong with that. Simple, cheap and very unlikely ever to go wrong.
At the time I had my S320cdi. Endless electric motors to raise and lower the squab, more to elongate or shorten the squab, more to adjust the headrests, more to recline the backrest, more still to adjust the lumbar support, and yet more still to move the whole seat fore and aft and yet more to raise and lower its height. Having set all these, and other motors to move the steering wheel in and out and up and down, and to set the mirrors, all the info can be stored in a little 'computer' so that at the press of a button all the settings can be returned to. Two other people can store their personal settings as well. And all that is repeated for the passenger seat.
Which is more likely to go wrong? A Mercedes where many choose complex gizmos or a Skoda where very few do?
Two points. One is that the more complex the beast and the more electronic options it has, the more likely it is that something will fail. The second is that we may prefer the more complex beast even if it does go wrong more often. I loved the memory seats being 6ft with a 5ft wife who loves driving.
All credit to Mercedes and Lexus that they both seem able to achieve high customer satisfaction despite great complexity. But neither have yet achieved complete reliabilty.
