2003 S600 questions/advice

I am considering buying a 2003 S600L
Does anyone have any info on this car or things I should particularly look out for?
Also, is it easy to remove the fridge from the trunk, I would like to take it out as it will give more free space.
Also, for Navigation, is there a nav CD or DVD that covers Hong Kong?
Thanks!

do you know if its possible to remove? I previously had the fridge in my 7 series taken out, however it caused the rear a/c to completely stop working, and screwed up quite a number of things.
I am hoping that this is its own system and its removal wont be a problem.
