Vaca,
Well, firstoff, pulling to the right is better than pulling to the left.
I have a friend who has a new Toyota pickup that veered sharply to the left when you removed your hands from the wheel...
Anyway, the first thing I usually do when a car is pulling is the cheap and easy thing...rotate the tires. I've found that if a vehicle is pulling to the right and I swap the tires left to right (can't do that with directionals...) sometimes the car will then pull to the left. That means the tires are shot. This is what happened when we purchased my wife's Civic. I put new tires on it and it drove straight.
So it's been in for an alignment twice...I have to assume everything is in spec. Try the tire trick...it'll only cost you half an hour...and you should rotate your tires frequently anyway...depending on how long you wait to change your oil, every oil change or every other oil change.
