First Car, RSX HELP

Ok so heres the deal, im looking for a car and i'm fairly new to this stuff. Ive narrowed my choices down to an acura rsx. Now my questions are to anyone who is familiar with these is what is the difference between the rsx premium and the regular rsx. I also am looking at the rsx type s which i have checked and it says it has 40 more hp and a little bit different body and options. So to anyone familiar with rsxs whats your opinion on them, and or experiences with them. One more question as i am completely new to cars, I am only 16 is the jump from 160 hp to 210 going to make a huge difference, I wont be racing, but id like to have a little bit of power for the odd time i need to make time.

Thanks,
Travis
