The reliability of the original model A is that it can be adjusted, fixes along side of the road.

Do all these “modern improvements “ actually make the car more reliable than a car mechanically restored to all original tolerances and specifications or does it become a old car that has to be towed?

True what you say, but how many Model A's are "restored to all original tolerances and specifications". Some of the items Bob mentioned are more for safety, like better lighting, window glass, etc.

Personally, I would rather not be on a tour when someones wiring has a meltdown because the wires have no protection (fuses). That's pretty difficult to fix on the side of the road.
