A first time driver needs a safe car that is easy to drive. The Dodge Intrepid isn't the easiest car to drive, due to the large size. If you're driving where there is very little traffic and easy parking, the Intrepid is fine. Just make sure the transmission is good and the engine isn't leaking too badly. If you are driving in a more congested area, you may want to think about the Stratus. Both are very cheap to buy used, parts are cheap and if you get in an accident, it won't be very costly.
Good luck!
