hmm its all about preference.Personally i like the is300’s and ive been trying to find one for quite some time now.The only negative things ive heard about the is300 is that it gets from 18-22 mpg and the interior has some plastic pieces that dont quite match up with the rest of the luxuary options the car offers.But then again the m3 is an m3 lol.Just research each car and figure out which car has the options and results you want.
