Cars/Trucks are no longer designed/built for serviceability by the "outhouse mechanic" nor will they ever again be.
Too many specialized tools are required and automobiles no longer require service as frequently.

The Porsche. Boxster is the most extreme example of this.
My understanding is that you have to lift the entire body off to change the spark plugs..

My C6 is an example of extremely easy serviceability. Everything is easy.
Easiest car to work on I have ever owned. No joke.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
