Cheap beater cars that can be ecomodded...first that comes to mind is the Toyota Echo. Super cheap, even cheaper insurance, and great MPG. A Civic would be great too, except that when you're looking at the sub-$1000 range a lot of the ones can be beat up ricer cars (thanks a lot, younger generation
....oh wait, I'm part of that younger generation. Ecomodding isn't rice is it???)
But yes, driving style really does count for 90% of your MPG gains! Most of my mods are removed temporarily at the moment, and with just a grille block and air dam I'm getting well over 50 MPG during personal driving in my '04 Civic sedan (automatic too). The Honda Fit is a great little car too; if they came as a sedan I'd be all over one, however the hatchback style isn't aerodynamic enough for me.
...And by the way, welcome to Ecomodder!
