Dealership explains no need for alignment

[jmjonesey]

I bought my Yaris brand spanking new with 18 miles on it, and after i got it on the highway, i noticed that it pulls ever slightly to the left. I figured hey, whatever, and before I even hit the 800 mile mark, I took it in for an alignment as per Toyota's warranty (which says any alignments need to be done before 1200). The odd thing about it thought, and they even gave me the alignment paper showing that it is off by no more than .02 degrees thrust angle (which is practically dead on) that the reason it pulls to the left is because being a smaller car it does not have positraction and the transaxle just does this. I figure they cant be lying to me because I walked around back of the service station and even saw them performing the alignment.

Is anyone else experiencing this phenomenon? What do you guys think?
