I bought a used, formerly $70k Audi A8Q. Leaking from every pore. If you don't wrench you can't own an old German car, it will fucking rob you blind. This ain't cheap as it is, but it's a shitpot more car than I could get from a stealership for the same money.
I have the full service history (with receipts) for this car. It has had practically everything done, down to a new transmission. Had a timing belt 50k ago but the coolant wasn't properly maintained so the water pump failed, so I just did one of those.
Basically, german cars have been unreliable as shit since the 1990s, when they went full-balls-electronic. Before that, they really really cared. Features like snap-together connectors with soldered-on pins, that you could order separately and cheaply (packets of pins, individual connector shells) and easily replace in the workshop. Now you need a $2k kit to service all the different snap-together connectors. Instead of putting the connectors someplace sensible and protected, now they're just all waterproof connectors. So when you get some kind of fluid leak other than coolant, now you get a terrible mess that you get to clean up with about four different solvents.
If you're not wealthy or a mechanic you can't afford to own a German car.
