It's Driving Me Batty

 BMW convertibles have batwings.

Yes, batwings.

Despite that renown German engineering, they are just not well designed.

They crack.

They break.

They need to be replaced.

The repair is not easy, and it is not for the faint of heart.

Replacement parts ain't cheap.

What's a batwing?

I'm glad you asked... 
It's a little plastic part with strings attached (It seems that there are always strings attached!) that helps hold the headliner taut when the convertible top is up. 

I won't tell you how much BMW charges for this part, because you wouldn't believe it. And nobody else offers it, except for BMW. They obviously planned it this way! But I'm not complaining. We now have five German "Otto-mobiles" in our family, and four of them are BMWs. We know what to expect.

Holy Bat Trap! This thing is quite a puzzle. Besides, we like a good challenge. It took hours of trial and error, as there were not any instructions included with the replacement part. We searched and searched and finally found a step-by-step description of this repair on one of the BMW forums. The instructions were not perfect, but it was better than "winging" it on our own.

Batman and Robin ain't got nothin' on this dynamic duo. 
These two are superheroes when it comes to auto repair.

If this part ever breaks again, we will surely send up the bat signal.
