and then selling them at auction with 100,000 ... However, their real mileage was sometimes as much as four times the odometer readout

These numbers matter more here. The Cummins/Allison engine/drive-train in these vehicles are otherwise good for 1 million miles before rebuild on average until they are used as delivery trucks. The constant stopping and starting used as delivery trucks cuts that number down to around 480k miles. So they are selling vehicles that will require engine and transmission rebuilds in less than 80k miles. That's very shady. The engine rebuilds are usually around $10k same as a refurbished engine and the transmission rebuild is around $3k. That does not count the cost to install them.

What's the difference between a rebuilt engine and a refurbished engine?

Effectively the same aside from time if you are waiting on yours to be rebuilt. One is the engine you have that needs to be rebuilt and the other was rebuilt because someone did a swap and now its inventory in a shop that sells refurbished engines.

[Edit] Adding jaclaz's very good point that one might be able to save money rebuilding their own if it requires less parts.
