I'm looking for an E39 for everyday use and mild club activity. I'm an old CCA member, been inactive since 2004 when my 87 E28 535is was totalled. My heart says buy a 99-01 540i/6, My head says buy a 01-03 530i/5. Is there a big difference in repair costs between the two? What are the non DIY issues I should look out for? Does the 530 have enough "giddie up" or will I have regrets? I have so many questions. Any thoughts, suggestions, I know I'm not the first to have these questions.
