John is a very good guy and would trust him with whatever he recommends. If he says it's in good shape it will be. Sounds like a real good deal to me.
If you don't get it, let me know! :-)
Check with John for a recommended enclosure size/type for you car. I think 1.5 cubic sealed would be ideal, but he has more experience with the sub than i do.
I'm surprised he responded as quickly as he did. He is being overwhelmed with orders right now.
