I like this one:
"At 30,000 miles I had to replace the front brake pads, which I am told is normal - who knows?"
Its like consumer reports, get some brake dust on the wheels and people complain.
Most people don't give a rip about how a car drives or is built. They just want it to run as cheaply as possible while they own it, and if it has the right badge on the hood they are happy to own it. Thats why Lexus exists and why BMW includes everything for the first 50k miles.
Here is a good one:
