Driving directions from Sevilla to Cadiz, Cadiz to Jerez?

Question

I am living in Sevilla, and my family is coming to visit. I was hoping to rent a car and drive down to Cadiz, and then hit up Jerez on our way back. We do not want to use the buses, so don't suggest it - I know how affordable they are, but they're an inconvenience and my family doesn't travel well in buses. If you can't give me directions, a website that would be able to help me would be useful. Thank you! Oh, and any cheap and reliable places to rent a car in Sevilla.

This one is Spanish.

When you are typing in departures and destinations for any of them I would suggest the ayuntamiento as these will take you to the heart of the cities
