Hi Brandon once you drive the Z you will forget or won't mind about fuel cost and repairs its always a thrill to drive and the desire to modify it is so irresistible like an addiction.
I drive my Z early morning on weekends for no reason at all just wanted to experience the rush of adrenaline. Its like a bullet train!
