I agree with what has already been said. Personally, I specifically don't use my VX as a DD because of the MPG issue. My VX is only used for pleasure outings, highway cruises, inclement snowy weather or the infrequent trip to the mountains to venture off-road. My DD is a 1980 Ford Fiesta that gets 41+ MPG and I only paid $1K for it.

For the very best possible "highway" MPG in a VX, get a set of lightweight P255/70R18 (32" O.D.) tall & skinny tires with an H/T tread pattern that has a center tread rib and inflate them to the Max PSI Per Tire Sidewall Panel. Drive your VX like you're hauling fragile eggs, lift-off early before coming to a stop, put your transmission lever in Neutral while sitting stagnit at a traffic light, and gently ease onto the gas when pulling away. In addition, try not to disrupt the sleek aerodynamics of the VX with roof racks or exterior-mounted fullsize spare tires. You'll be amazed at the differance in MPG you'll get.
