Looking to buy a 6 CD changer for the boot of my late 1997 BMW Z3 2.8. The car has been pre-wired for the changer but, as far as I can see, one has never been installed. I am happy to get the bracket and other minor components from an on-line BMW agent as necessary but would like to save some funds by getting the CD changer unit itself (and cartridge) second-hand. If you have them and are prepared to sell, please get in touch.
