Yeah, that's pretty much it.
With one wrinkle: The EPA has changed the way it estimates MPG. Starting in model year 2008, estimates reflect the effects of Faster Speeds & Acceleration, Air Conditioner Use and Colder Outside Temperatures. The tests lower MPG estimates for most vehicles. (the vehicle obviously gets the same mileage no matter how it's tested, but there's less of a spread between the estimate on the window sticker and real-world mileage now)

I wish more people would sit up and take notice; they'd be a lot more likely to turn a deaf ear to the Big 3 whining about it being infeasible with today's technology.

- R-12 air conditioner converted to R-406a. Saved ozone and money
- 4.1:1 final drive converted to 3.4:1. Quieter, better mileage but it's a good thing I live in the flat Midwest.
