I've put over $5,000 into mine in the last six weeks and have several thousand to go. What's interesting is that I bought it new in 1971 for $4,335. At that time, I paid about $600 over sticker to jump to the top of the nine month waiting list. The Z has been in storage for 15 years and I've now replaced all of the deteriorated items like brake & clutch cylinders, tires, door seals, ignition, etc. Next, to the body & interior. What fun!
