Another Question for Mr. Hyundaitech

The pulling on acceleration is indeed a common occurrence on front drive cars and is called "torque steer." It varies in severity from vehicle to vehicle, but in most cases is quite normal.

As for the drifting, we'll presume your steering wheel is centered and your alignment is within spec. If the car tends to actually begin steering toward one direction or the other on flat smooth pavement, then it's likely a difference in the rolling resistance of the tires. Often, rotating tires will reduce or eliminate the condition.
