I got the vx not but maybe 3 months ago. so as far as mods i have not done any yet other than professionally installing the Pv muffler. i got it with P255/70 r16 yoko tires on 15" eagle alloy rims. (not really sure what that means but i got it off the tire) as far as a lift goes, neither previous owners have told me that they have lifted it so as far as i know, it is not lifted. (anyways of quickly checking?) the only other thing that i could possibly think of if it does have a roof rack on it. it has been taken care of very well and has not missed any scheduled maint. so.. maybe something might be wrong with the engine?
