My dream : an insight 1, preferably a manual one. It's old enough so you can get one at 3-5000$ and you may double your FE, ie 2500-3000$ saved/year. As you are driving mainly on highway you can get one with a
dead battery as metroMPG did.
At this rate you may keep your Tacoma as the second car when needed (cargo and/or 3+seats) with the lowest insurance.
