Hi. I've been preparing myself mentally for my purchase which looks to be in January. I've been reading my parts and workshop manuals and saw that on an automatic, (that's what I'm getting), there is a final drive fluid that needs to be checked/changed. What my question is: does this need to be changed as often as the trans fluid and what type of oil is used for it? I didn't even know about it until I read more of the workshop manual. That what scares me the most - finding stuff I had no idea even existed in the Delorean that needs maintenance. Johnny
