.........Would you register a complaint about such a suggestion?
No, I'd raise my eyebrow at the guy and say that's not an acceptable answer for a problem with a luxury car. I'd wait for him to respond appropriately, but would still ask to speak with the GM about the issue if I wasn't satisfied. Always be polite, move up to the next guy in command, and remain convicted.
Either lead, follow, or get out of the way...
Audis don't get out of the way and they never follow.
