Id believe it more once its time to install. I would imagine you saw a screenshot of it being unmarried but i still had issues installing mine, causing me to contact hypertech to fix it. But if it does work properly that is an awesome deal.
i bought a full tiburon drivetrain with less then 12k miles for $20 bux years ago. no one else ever tried to outbid me, and there was no reserve. got to love newbie sellers!
