My question is for anyone familiar with Potomac German Auto in Frederick, MD. I'd like to know if you can walk in, ask for a part, and then choose one of them yourself from stock?

Sure, I could call ahead and ask about this, but I just want to gather other's experience.

My car has a loose, whining, worn differential, and I want to get one from a place like PG Auto. But, I want to examine potential replacements myself from their available candidates. Naturally I'd pick out the best one.

Will they allow that?
