I currently have a 91 325iC. I think I am going to sell it within the next few months and would like to look into a 5 series. What should I look for. I like the 2.5 liter engine but more power never hurts and I am interested in the touring version as well. I don't know much about the 5 series but would love any advice you all may have. I would like to stay around the $12,000. range if possible. Thanks.
