What are some of the most reliable European luxury cars?basically, any car which is properly maintain can last a long time. it just takes a lot of resource and the car ages. but here's my take:-
Porsche, especially the 911
Porsche tends to over-engineer their cars to provide maximum performance at maximum reliability. two-thrids of all porsches ever build is still running today.
Mercedes, especially the diesel and V12 engines.
mercedes diesels engines are overbuild and designed to last 20-30 years. the fact that mercedes 911s lorries from the 1960s are used to run and carry loads today is a testament of their durability. there's also the G-wagen and umigod/actros truck which design is basically unchanged (with minor improvements) over 30 years shows how over engineered their cars are.
I'm a Mercedes fan myself. I've had the older ones for 10 years now and the maintenance is not as scary as people have you believe.
I'm a chef not a mechanic and I do all my own maintenance and replacing parts if needed.
Currently I have a 1995 c220 and I'm only starting to replace some of its parts now like
- alternator (1yr ago)
- starter (6months ago)
- aux coolant pump (cleaned and rebuilt 2months ago, working great)
- feel pump haven't replaced still working fine but a little noisy
- Water pump (1yr ago but not the original)
Other parts will never need replacing if mainrained properly.
Only one bad, very bad unreliable bit is the wiring harness plastic was made from some biodegradable plastic that has started to flake off. This is a worry in alot of German cars from 1994-97 as it was a German government idea.
