What to look for in an alignment shop?

I found that the older guys (50s-60s) Have special knowledge that the younger folks don't have. The older guys have a sense of what works best on the older cars regardless of specifications (although specs are important).
Every “older” guy I’ve seen aligns to Oe bias ply specs an have clue about handling, modern tires, etc.
find a European car shop where guys are used to aligning cars for performance.
