He probably wanted to know about your training because there was quite a bit of misdiagnosis on your own vehicle. And as I'm sure you and everyone else knows, almost anyone with tools can swap parts but only a real tech can diagnose without replacing anything.
What Nissan store in Albuquerque do you work for. I worked at Melloy for quite a while and was Shop Foreman at Garcia Infiniti as well. If you're at Reliable, I'm sorry. Great to see another NM guy with an s30. Check out the Albuquerque Z club, they're pretty knowledgeable cats.
Looks like a great shell, hopefully I can see it in person someday.
