I'm looking for a 3 series, 4 door, automatic for my daughter. Finding lots of 2004 to 2005's in great shape but with high miles. Most can be had from 4000.00 to 7000.00 range. Are these prone to transmission problems? I thought I heard somewhere that they are. Any other big repair issues that I should be aware of? I know I'd be better off with a Honda, Toyota, or Nissan so please save the suggestion, this is what she's hoping for. She's a good kid that's a straight A student, I'd like to get her what she wants. Thanks
