My wife yelled at me when I told her I was considering a diesel Jetta. Said she, "They're dirty, smelly, and loud!!!"
Now I laugh at her at the pump--I get something on the order of $0.10 per mile, while she's still at $0.12 a mile in her Pontiac Clowncar^H^H^H^H^H^H^HVibe.
Still, she prefers her Pontiac.
