Bill, Anemic is the best for good mileage. I'm always stressed going 80 in the Monterey. You have a very complicated smog system to fool with. Well of coarse if you want to fool with the exhaust and don't mind yelling at each other over the sound it might be worth it. Natasha wears the hearing protection that you would use for a chainsaw going up hills and wears a microphone so I can understand her.
