Darryl is a really good friend of mine and he is straight up legit! He is a tt.net veteran and owns a 96tt that was built by the original SGP Racing back in the day. You have nothing to worry about go for it. I am sure he is going to ask you if there is anyone that would like to buy his Z as he does not drive it anymore and it is really nice except for obd2 but he has it at 95 spec for the power upgrades. He is an original member of clubz.org from the bay area in the late 90's.
