Agree, and I have known a friend to cause his E38 gearbox to die prematurely. His gearbox got a leak, and kept losing small amounts of transmission oil, and out of laziness, this person didnt get it fixed.
Eventually the gearbox overheated and siezed. It cost him a lot of time and money to replace the gearbox. Having said that I also purchased a used Honda Accord once, with a problematic gearbox. Ofcourse I didnt know about it at the time of purchase, and had to be replaced at a cost.
