Hi folks,
I am new to this forum and need some instructions for my newly purchased '99 Z3 M with 15,000 on her.

How do I keep from creasing the rear plastic window when dropping the top???
Would like to either apply some 3-M protective plastic to front end and sides or add a bra and would appreciate some input as to the wisdom of making either choice???? Where is the best place for purchase?
Thinking about adding a 6 CD player to my ride and would appreciate info as to how to install and where is the best place to purchase a unit?
Sorry about all the questions but I'm wild about this car.
Thanks in advance!!!!!
