That information is interesting and concerning.

I called the Montgomeryville, PA Firestone 267-436-4123 and just asked if they can do a four wheel alignment on a Chrysler Crossfire. Tim said yes no problem.

I then explained I had the lifetime alignment warranty, and he asked when I would like to schedule the visit. I declined to do that right now. You can certainly call the store and verify the information and talk with Tim or the manage Michael Pietrowski.

So, if you are still in an agreeable mood, at this point I would expect we can agree that some do and some don't.
I would have to dig around at home to find my actual alignment printout, so I'm attaching a sample which looks like the one given to me by Firestone. It has the before and after measures for Camber, Caster, Toe, and Thrust Angel. They look up the car in the alignment computer, and it provides what the specs are, and shows the measurements before and after any adjustments. That works for me.
Let's not forget adjusting the rear camber requires an aftermarket solution, so I installed the adjustable camber bolts before they did the alignment. The first tire shop I went to for the alignment suggested I take the car to a body shop to fix the alignment because they could not adjust the rear camber.
