This is how I go to Mars using mostly existing products.

Put a really long boom on the iss and a nuclear propulsion system on it.

Modify a falcon 9 booster. So it can get to the iss itself. Then refuel it, attach a crew dragon to it, and attach it to the iss. Once in orbit. It will land on its own and be the ascent vehicle. To return to the iss.

Decent will be a separate crew dragon with propulsion landing and air bags.

The surface hab, rover, and everything else will be sent by FHeavy launches ahead of time.

4 man mission. 2 stay in orbit on the iss. The other 2 go to the surface and back. They have to fight to decide who gets to land.
