Washington state
I purchased this Z new in April 1978; original interior in excellent condition, original engine and drive train all working well. All gauges and controls work; paint is decent for being 40 years old, has some mostly coin sized rust spots but none in the wheel wells, foot wells or spare tire area. More info. at the CL listing, see link. 211k miles, price 13000 negotiable.
