Congrats on the Mirage! Did you go for the CVT or manual shift? (Didn't see it mentioned.)
I've test driven both, and they're very capable machines in the MPG department. Future EcoModder classics, without a doubt.
Mitsu did a decent job with
the aerodynamics of the car -- 0.28 drag coefficient is better than average for this size & type of car. But there are still a number of easy things you could do to improve that. And
much more improvement if you're not worried about making the car look "unconventional".
