What is the difference between the Ford Transit Custom and the standard Ford Transit?

I'm looking to purchase a Ford Transit for my business, but I'm unsure of the differences between the Custom and the standard model. Can you provide some insight on the technical specs and features of the two options?

The Transit Custom has a more modern design and sleeker appearance compared to the standard Transit. It also offers a wider variety of engine options and has a higher payload capacity.

The Custom has a lower roof height, making it more suitable for urban areas with height restrictions. It also offers more advanced technology features, such as a built-in navigation system.
