Well, it just depends. Do you think you have the responsiblity to handle a performance car? Just because you say you wont drive fast doesnt mean you wont, there will probably be a time you'll drag race on the street and hopfully you wont crash and kill someone or yourself, remember thats a big thing to think about and to live for the rest of your life if something goes wrong. Also how do your parents feel about it and more than likely your insurance is going to go up. Not trying to scare you or drive you away from getting a fast car trust me i felt the same way when i was 17. Just remember driving is like handling a loaded weapon it only takes a split second for something to go wrong. So think about it real hard, if your not rdy to drive a hi-po car with a 5spd maybe you should wait.
