My experience with alignments is that most vehicles have specifications that say "if caster|camber|toe is set anywhere between here and there, it's fine."

Most alignment shops will take something that shows outside of the "here to there" range and change it until it's just barely inside the range and then tighten things down and consider themselves done. It doesn't matter if the two sides of the vehicle are at opposite ends of the ranges. And for most folks and/or most cars that might not matter (because the cars are sloppy or the drivers don't know and don't care).

I notice and it bugs me. I want the settings as close to the same from side to side as possible.

I've gotten alignments years ago where the settings were in the green zone, but radically different and I had a pull and the wheel was cocked to one side. I'd go back and say "this is wrong" and would then get told "we aligned it to help when the roads are crowned" which, IMO, was total BS, because I'd just driven on several different roads and the car drove like sheiße.

I'd be happy to pay more for a good alignment (by going to a good shop), and do when I can.
