I have been making the same comment for years now.
One of the best thing you can do to your car is to keep driving it regularly.

If you park the car for months, start and then keep running the engine without driving, wash the car and don't go out for driving, etc, all these won’t cause immediate problem but slowly and gradually accumulating the tiny-tiny minor defects and one day, eventually, it will emerge as a big issue.

It could be in 1 year time, 3 years, 5 years or even 10 years time but it is biting into your chassis and engine.

With this NSX, it was the failed IG coil tube plus the condensation around the IG system.

Although the spark plugs were replaced few years ago, all six of them were in very poor condition.
In fact, at that time, the issue with the IG coil tube should have been spotted....

When you pull the IG coil off the plug, normally, you would feel some friction.
With healthy IG coil tube, you would even hear the 'pop' of vacuum pressure.

When I lifted the IG coil, I felt no friction at all so thought strange and used the mirror to look inside the plug hole.

I saw really strange plug top terminal so decided to take photo.
