Just a general observation regarding 'German' cars.
Do I think they are 'more reliable' than other makes and brands?
No I don't.
My reasoning for this is as follows.
I'm lucky enough to drive 'high end' vehicles as part of my business/profession. Overwhelmingly the cars I drive are German. My daily driver WAS, for example an R32 Golf(Mark 5 I think) with DSG gearbox.
That car had a known fault from VW from the day I drove it. Namely a faulty gearbox problem to do with (all) DSG fitted cars. Was the car fixed under warranty?
NO!!
The problem is that in Europe, the fault 'only applied to a few hundred cars' that were fitted with a faulty component. All the other cars, outside that batch aren't deemed to have that fault so no warranty cover.
VW usually have a 2-3 year warranty. That R32 Had covered less than 30,000 miles by the time the 'fault' developed. The car was serviced on the button and never 'thrashed' (I'm nearly 50 so those days are behind me)
HOWEVER, if you look at the United States ALL DSG fitted cars have a 'lifetime warranty' referring to the DSG gearbox ALONE. That is because 'litigation and people power' have forced VW into this route.
In Europe you are treated as a c@@£!! Sorry for the 'expletive'!!
I also get to drive Mercedes on a daily basis. That could be an S class limousine (128,000km) a Mercedes ML 320CDI 4 Matic(140,000 km)/ SL AMG 63(42,000km) AMG ML 63(45,000km) Porsche Panamera 4.8 Turbo(20,000km) Porsche Cayenne 4.8 Turbo (Minimal kilometres)
ALL of these cars are serviced 'on the button' and looked after very well.
With the exception of the AMG SL63 and the Porsche Cayenne Turbo ALL the others have had serious reliability problems. So parts on the older cars have worn out quicker than you'd expect, the ML 320 4 Matic has had its suspension completely replaced at a cost of €6000 recently. The S class has also had the front suspension replaced(€1800)
The most unreliable car, in my experience is the Panamera.
Mainly due to sensor problems and engine management lights etc coming on.
The car had the cam cover and alternator replaced by a factory recall when the car was only 3 weeks old.
So are German cars more reliable??
It's a load of old' tosh, in my book.
I have an old Jaguar at home in a lock up that starts and runs with minimum effort....
Okay, maybe more effort than that in truth............
