2006 GT Alignment

[WVOHVANCFL]

I recently drove my (new-to-me) 2006 GT Convertible on it's first road trip, maybe 300 miles total. (62,000 miles from new - very showroom stock condition).
At interstate speeds (55 mph), JUST KIDDING!
At interstate speeds (70-80 mph) there was very slight unbalanced feeling in the ride. It was not vibration in the steering wheel, just a sensation that something wasn't right. It also pulls very very slightly to the left with hands off the wheel.
I just scheduled an alignment and wheel balance/rotation.
The shop asked me 2 wheel or 4 wheel alignment ($59.95 or $79.95).
Is this question answered just by how much money you want to spend, or make/model, or some other factor(s), like FWD or RWD?
Thanks in advance for any input.

Have them look into Front Suspension issues. Those have Hydro Bushings in the Lower Control Arms that go bad. When they go bad they can throw off the alignment and also make noise.

2 wheel align. There is no adjusting the rear stick axle.

Make sure the tires are installed with the proper side out (usually indicated on the tire). I just had a shop install 4 new tires but 1 of them was installed the wrong way (on front left) which would pull the car to the right with hands off the wheel. The shop manager apologized and verified that the wheels would pull when installed incorrectly. At least it was an easy fix.
