Not sure if the OP has bought anything yet... or how close you are, but if you are traveling in the city a small/small car is fine. If you are commuting on the highway with it, go with something a bit bigger like a Golf. Safety should be a big factor in your decision. Second hand is also better IMO. My last few cars have been dealer certified used cars. A good place to get a Mini or Golf with a 2 year warranty.
