How the hell am I supposed to drive past gas stations with only an 11.1 gal tank?

This is pretty funny. BTW - I don't think it would be that hard to swap a larger-capacity tank from another Toyota vehicle. you'd need to figure-out the max dimensions that would safely fit and ensure that the pump/pickup were either the same or could be fitted to your existing wiring/fuel lines. I think the Camry and/or Corolla have similar-but-larger tank setups.
