Do it! The whole reason I bought my civic was for the gas mileage. Its not even that spectacular, I get about 28 mpg city driving. But switching from my suburban to the civic to deliver pizzas has PAID for the civic in less than 5 months! Though it will take longer for the VX to pay for itself it still should with gas prices continuing to rise. I say take the tax money and pull a loan for the rest and get the VX in addition to the HX. Having multiple cars is awesome
