Confronted with that, I'd seriously think about selling the car. I just don't have the patience for stuff like that anymore. And I certainly wouldn't be paying some mechanic several hundred dollars (or more) just to change spark plugs.
Cool cars, but just got added to the list of ones I'll never, ever buy.
