Like I said in one of my other threads..I ordered a 6cy Terrain SLT1 but I am gonna get a [email protected] when mine gets here..The dealer said he can swap it out for what I want..I am still stuck now after reading many things about 6 or 4 cylinder..Tapping in Engine(not sure if just a 4 issue?) engine running ruff in Econo mode?? I know the terrain is heavier than my Rav4 4 cylinder but still wonder if a 4 cylinder would do me good..I am always afraid if i get the 4 and not satisfied i would have wished I got the 6?? I am wifey as passenger..thats it..no towing..Any input would greatly be appreciated..I also heard that when u give the 6 the gas it kinda hesitates??I really am in a quandry about this that why I would like to hear from Terrain owners both 4 and 6 cylinders....
