i promise that you would be really dissapointed in the power and gas mileage of BOTH of your vehicles at high altitude
makes your car feel really sluggish (just got back from sea level with my VX)
i gotta say, i have never felt a VX at sea level. the lowest mine has ever been was moab. but it felt like a completely different vehicle. it was actually fun to drive, usually i just feel dissapointed when i step on it in my VX trying to get over the rockies. (it pretty much just revs up a lot and doesnt get any faster at high altitude)
