My line of work crosses paths of many people who drive nicer cars than I do and being the car guy that I am, I ask them about their cars.
Invariably, its the German cars that provide the horror stories. Its not that the car breaks down that troubles me, every car has problems. Its the scope of the problem, and the cost to fix it that blows my mind, and people view this as normal and acceptable
1) Audi S4. Clutch and tranny "blew". Dealer wants up to 10grand to fix.
2) Mercedes ML(?)... "it was a great vehicle until the turbo went on it. $8000 later, I sold it off and bought a vehicle with a normally aspirated engine"
3) BMW 3 series convertible.... "the top failed, dealer said I had to order an entire new top and motor mechanism, quoted me $22,000 and it would arrive straight from Germany"
4) BMW ML.... led driving light.... "a stone hit it, they want $550 for a new one"
