Help thinking about buying a is300

Hey guys im new here and lately ive been considering my next car to be a is300 but i dont know i keep having second thoughts cause im only 17 and im worried itll be to much for me to handel like im worried im gonna loose control of it or something since its rwd and stuff and i dunno how high the insurence will be even if im under my parents name. So my question is you guys think its to dangerious for me to have a is300? will the insurence be to high? should i stick with a audi a4 1.8t since its AWD and probly a safer car? I want to switch to something better than my escort because i wanna keep the car forawhile and i need something reliable and what better than toyota/lexus.

Thanks

Yes a rwd car like the IS300 is not the best car for a new driver especially in the snow. Also the insurance will be quite high. Also I am curious how a 17 year old can afford such a car because I am in my early 20's and make pretty good money and I can't come even close to affording this car, not even a used one.
