The S30 generation Z styling was lead by Yoshihiko Matsuo and it set such a high bar for the competition, that it never really had 2-seat competition from Japan during its production life. You could probably argue that the competition came from cars around the globe, but the Z offered a great combination of driving experience, quality, and entry price.
This one was an engine from a later 260Z, which means it has a 2.6 liter L26 inline-6, which when fed via twin Hitachi HMB 44 mm SU-type carburetors is rated at 162 horsepower and 157 ft-lbs of torque. If the rust (as mentioned) isn't too bad, this could be a nice driver for the money.
