Is this your DD or a secondary car you get to use for fun driving when the mood strikes you?

I would get the Toyota MR2 with high mileage and a low price. That said, I am always one for a bargain, if the deal on the salvage title 350Z is great (and since your buddy who is a tech already checked it out) I would grab that one.

My answer will definitely vary based on whether or not this is your DD.
