The best thing is simply to ask someone.
Fares are $700 to $900.
Driving by own car is not recomended. Traffic is horrible, although I like to drive there... you have to pay highest attention at all times and know the streets to be succesful. Another problem is parking. Use parking lots or at least spaces which are guarded by anyone to avoid your car being robbed or something else...
The best and easiest way to get around is using Transmilenio, the new bus-system of Bogotá. At the moment there are only three "troncales" opened: Autopista Norte, Av. Caracas and Calle 80. But more are under construction (like Cll. 19) or will be build (like Av. Quito[NQS, Av.30] or Av. Suba.
As Transmilenio has its own lanes it passes every traffic jam, which might be the most important advantage.
Single-fare is $900.
