Awww, Z cars are that bad to keep running. A lot like the RX in that there is a ton of race knowledge out there about them. Brakes require a lot of maintenance, and the valve train, but that's about it and they are very easy to work on.

Only parts issues we have had are strut tubes (which can be found used) and alum rear drums, which apparently are moving production overseas and should be available again shortly.

Finding solid straight tubs is probably the hardest part.
