i dunno how big the 6 is in the tacoma, but if its a rather small six, id say neither are worth it, the X5 3.0 is useless(just my opinion) and a truck w/out 4WD is also useless.... can u get a toyota tundra, i think those are a little better(may be same price as x5) or the Nissan Titan, but those r kinda expensive
