Did you get it? all those issues are with the tailgate harness, a common failure on tourings. YOou coudl buty a new harness for several hundred dollars, or spend 30 minutes with a soldering iron and heat shrink and fix it yourself.
Price was very good for a touring. They're rarer than say... a z8 or e36 M3, and more practical than an SUV> In the last year or so the prices have started moving upwards compared to sedans to reflect this.
Oh and it's an M50... no timing BELTS
... it has timing chains. (EDIT: I MISTYPED IT MYSELF!!!
mine has 180+k on it... there is no problem with the m50 in a touring.
