Now we're talking about gas mileage and "MPG on the track"?
If the gas cost is the concern, you sure as hell can't afford the tires and brake pads and the paint damage from ending up in the gravel trap.
I suppose if you're talking about performance in road race/track events that require a pit stop it's relevant but now we're about a thousand miles from the concerns of 99% of the buyers of both cars.
To that point... Of the small percentage of people who will do more than drive it to work or go out cruising, the majority will be doing:
- Drag race
- Autocross
- HPDE
I'm sure a pro in a well-set-up Camry SE could probably mop the floor with most drivers of either a 370Z or a Mustang GT in any road racing contests, so really what we are concerned with here is factory setups being used for things most of the buyers will never do anyway, and which, if the car were actually used for that, would never use the factory setup anyway, i.e. "******** magazine racing."
I'm sure there are a few drivers who actually race both cars. I'm sure they can both do very well. But, for most buyers, getting all caught up in this "which car turned a faster lap at Laguna Seca" is kind of retarded, because as much as we all like to think of ourselves as little Mario Andretti's, most of us would be getting passed by a good driver in half the car, or going into a wall at the first turn.
