I think he was trying to argue that "good" is subjective. That Ferrari/Porsche aren't necessarily good, as it depends on what you value. If you value simplicity and reliability, perhaps you would view Toyota/Honda as superior.

Actually, Porsche has been #2 in reliability (J.D. Power Vehicle Dependability Survey) for two years running (behind Toyota's Lexus brand), #4 in 2011, and was the leader in 2010.

However, to be perfectly fair, your average Porsche sees far fewer miles per year than a bread-and-butter mid-size sedan.

They're perfectly usable as daily drivers.

Guy on my block parks his 911 Carerra 4S on the street, drives it every day. It makes me happy that he actually uses it, and also makes me feel better about parking my normal car on the street.

They're not exactly exotics or anything. If he DD'd a GT3 or something that would be more impressive.
