I went CRX-HF the high effency model, there hard to find as many ricers rip out the low HP motor and drop a big v-tec in it to match farrari performance.. There fast as hell but dont get the best MPG then..
Watch this crx.. blow awa a lambo!!
IF you can get a CRX-HF in stock condition and not rusted up etc .. makes a great start as its the highest MPG car ever sold inthe US..
Next I'd say geo metro.. then civic hatchbacks.
