hunter is200

hi peeps i was lucky to get my hands on a black lexus is200 and thankfully its an auto coz ive only got one leg lol. me and my family are all petrol heads and always arguing whos got what bhp and torque etc. i cant seem to figure my girlie out as it has the sports grill it pulls harder than my partners manual, (he reckons his is faster?) and i have a pwr (power) button? does this mean mine is the sport auto or standard and what are the power stats? its bugging the hell out of me; when i had 2 legs my partners manual was fast but my auto seems quicker in every aspect and if the power button is on then it throws you back in your chair. please help peeps. many thanks one leg lol x
