I have a beautiful 330ci, with only 74k on her. One owner. I need to source a new engine. I hear LKQ, Autobahn Parts, Bavarian Engine Exchange......but each place lacks worthy reviews. Where do you guys recommend I source a used engine from? Thanks! p.s. - before you start asking, "how did a bimmer with only 74k have catastrophic failure?", let's get a supplier's name first and then I'll answer the tragic question.
