Help me pick the best BMW for me

Here's the deal. Im under 25 and I dont make a killing but I do alright. I'm probably about average. I make about median household income in the United States, so I'm decent there. But I am a businessman, and need a car that looks professional. Furthermore, I am not that good in the looks department. Lets just say I literally look like a troll. I want a car that girls are going to love. Help me out!

I was thinking a gently used 328i. I dont need 4 wheel drive or anything like that... But definitely want the backup camera or other "luxury" look accessories. I usually like a white exterior. Would want beige interior. I could be talked into other color schemes though.

Help me out.

Professional looking car? Chevy Impala or Ford Taurus. They say "I'm here to work, not pretend I'm something else." Domestic brand says "I'm willing to work with American companies." Large car means customers aren't cramped if you take them to lunch. Speaking from experience, driving up in a new BMW, especially when you're young, can start conversions that you might not want with customers.
