Congrats!

First thing I would recommend (well, after basic maintenance / tune-up check) is take a tiny amount of that $3k you just saved, and get an MPGuino for this car.

You got the manual transmission, so you now have a huge amount of control over whether you're going to get 30 mpg or 60 mpg from this car (or somewhere in between). Instant & resettable trip MPG feedback is how you fine tune your driving technique to get the results you want.
