If a person was handy, with a little engineering, and backyard basics, You could build your own.
It would not be the same as the original, but if all cars were tested using the same tool, it would not matter.
A spring loaded steel plate, with a resistor and linkage attached to the plate reading through a volt meter, would give you a pull measurement in volts. (think controller).mount all that in a homemade box, and test away. The various strengths of the magnets and distance from the plate, would have a different pull on the plate. You could also build a fixture for just holding a magnet by itself at a given distance from the plate, and test individual magnets that way.
Just a thought?
