you can have a decent auto coupe for less then $25000 now a days, for this car, I drive both auto and manual before i bought one,
for daily the 5 speed auto is more than enough in terms of engine response or gear box response. When you get stuck in a traffic, you will love the auto box. For my experience in twisty mountain roads, the car provide great and easy control, very predictable limit and turn in.
If you must drive a manual, 350Z is a better choice if you don't mind it only have 2 seats.=)
