Make sure you get details about where all of your work and parts get subletted out to during your phone interviews. Ask many questions. As I said before, most shops are general contractors and send everything out. Very important to get many details about everyone who will touch your parts and restore them. Who are they, what reputation do they have, etc. Also ask if their work will fly at the Camaro Nationals in concours or Bow Tie judging. I travel every week to inspect cars for clients all over the country. Many are restored and just terrible examples as to being restored correctly.
You'll get 1000 opinions on this board, just make sure that you make the right decision for your car and your hard earned money.
