Somewhere in hell, there are a bunch of automotive engineers doing difficult maintenance tasks which they designed into vehicles such as bleeding the brakes on Ford Escorts, or spark plug changes on AMC Javelins (it actually required unbolting the engine and using a hoist to get at the last sparkplug).

How about this? No dipstick for the automatic transmission on a Mercedes. No way to tell what the fluid level was in it.

That is common on many vehicles.

I also remember some corvettes (C5?) required the side of the car to be removed to change the battery.
