Hi there AZ-Zbum!
TinkrsToyCo said that you would be the best person to ask about buying a Z31. I would really appreciate some help on deciding if the purchase would be a wise one. It is a 85 n/a, clean inside and out. The guy is asking $1600 for it. The issues I am concerned about are that the speedometer spins all the way around when driving, the oil and battery gages and cruse control dont work. It will also need new brake pads and when idling it goes back and forth from 650rmps to 1000rpms. I would really like some input from someone that knows about this car. Thank you so much for your time.
