(1) Bridgestone SO-3 Pole Position Tire with almost exactly 300 miles on it.
When I had my G35 coupe, the tire blew out somewhere in Winston-Salem, North Carolina. I bought this tire for roughly 250 dollars and got home on it.
$100
(6) Nissan Factory G35/350z Oil Filters (may fit other models)
Purchased like 20 of these from the dealer. I have 6 left. They are factory/oem in box. (1 was removed to take the picture but is in the plastic wrapping)
$20
