But the items mentioned by OP that resulted in almost $10,000.00 in repairs on a less than 5-year-old Mercedes aren’t exceedingly complex assemblies or parts.
My 14-year-old Tacoma is on its original engine mounts (rubber, of course, but the powertrain is very smooth; it doesn’t need fancy liquid-filled engine mounts), all original engine gaskets and seals (granted, timing cover seeps a bit, but a drop of oil has never hit the ground).
And, a design in which oil can wick into the wiring harness is bad design. Period.
It’s not just that the German cars are more complex. There are many egregious design deficits that lead to early failures.
I’ve noticed that you’re a tireless promoter and defender of Mercedes here. That’s fine if you know what you’re getting into and are willing to pay the higher maintenance costs.
Personally I really like how BMWs and Porsches look, and their design philosophy of performance and fit/finish first, etc. But if I ever bought one I’d have to go into it knowing it would cost a lot to keep one going.
Anyway, the advice you get here and in other places on the web is to avoid owning German cars out of warranty. Or lease. That’s because they tend to fail, and fail spectacularly, resulting in thousands of dollars in repairs.
Essentially, they’re for rich people, which ain’t me!
I like to buy a vehicle (not lease), and keep it for years and years, and extract every penny of its worth.
If I were to ever buy a lux vehicle, it would be Lexus. Because I know and trust Toyota’s engineering and QC. They really do focus on making a more reliable, longer-lasting vehicle, because of their very Japanese philosophy of saving face (as, I believe
@02SE mentioned a while back).
To build something unreliable or that needed big repairs after 5 years would result in their reputation being sullied, and people’s trust in the brand being eroded (as has happened somewhat with Honda & Nissan over the last several years).
Mercedes, BMW, and, also, Volkswagen, have a different philosophy. Their customers are primarily more wealthy, affluent people who tend to trade cars frequently. Or lease.
