Heres the situation, I currently own a Mustang GT with Saleen everything on it, its a converible, real attention getter and my first car, blah blah blah.....I am going to be selling it and considering purchasing an M5. My price ceiling is 45k. I was looking at both the M3 and M5. I like the M3 but everyone and their mom has when here in chicago. My buddy just got a black M5 and took me for a spin in it today, loved it. I am leaning towards the M5 because it has this "executive" look to it. I will be starting law school in the fall and also want something that I can drive in the winter. So, my question(s) are , What year M5 should I be looking at and why, and Will I be able to drive this car in the winter. Thanks for your help!!!
