Although it would be a long and difficult drive, the experience can be breath taking. You have to board on a ferry to pass the Darien Gap then pass through several borders. Just make sure that you have brought all important papers for your car and yourself when you decide to go on a land travel.
Some people would love to have a little adventure that only land traveling can give them. And passing several places on your way to Los Angeles can be very exciting.
Here's a link, this offers a ferry boat ride to Panama from Colombia with schedules and rates:
