JC Cosmo mechanical issues and quirks?

I haven't seen a thread like this before. I figured there's enough AU/NZ guys on the forum that we might be able to get some information.

Would anybody be able to chime in with what the common mechanical problems you have been seeing on the JC Cosmo and potential known fixes?

If I was to buy one, what are the key areas I would want inspected? What features tend to have issues over the years?

Any common maintenance parts that are becoming hard to find?

I am concerned over my ability to get things like new shocks/springs, bushings, brake parts, belts and hoses, etc. I might be willing to make a small stockpile if things are drying up.

Parts have almost completely dried up in Japan due to new junking laws encouraging crushing vehicles as soon as possible several years ago. They were rare to begin with, then hunted into near extinction for their unicorn horns. The resale value of good running 3 rotor Cosmo's is skyrocketing.

The issues seen over the years are:

The alternators like to take things with them when they go. Preemptive rebuilds are recommended. I lost a meter assembly, friend lost window motors, main computer.

Fuse block inside the vehicle is a problem child as well, for series I's.

Sequential turbo control issues are common, imagine that. The primary turbine is also twice the size of the secondary. Have seen some claim that you can run two primary turbines easily in the stock exhaust manifold.

The Series I's had an AC compressor recall.

The AC will stall the engine, if you come to a stop with the vehicle in drive, due to insufficient vacuum. It is like a built in engine compression tester.
