I have an old shape focus with the cd multi-changer - which is ok. It has the big buttons, is easy to use etc.
Personally, if I was going to upgrade, i'd get a cd player that plays MP3's, or if you're spending a bit more a stereo with a hard disc.
Ford do an MP3 player I think, but I don't know what the quality is like.
Obviously you have a pc, so if you know how to rip to an MP3 the bonus is that you can fit 10 albums on one blank disc at good quality. You're not going to scratch up your shop bought cd's in the car, and best of all - you get the names displayed on the player, which is better than trying to remember whether the track you like is song 4 on disc 3 or song 3 on disc 4 on your multichanger!
