For $19,900, I have an E39 BMW 530i on offer.
From 2003 to now, it has only done 80,000Km = 10,000Km/yr
And it's a Sapphire Black Highline Individual 530i - built in 2003.
In Wikipedia, http://en.wikipedia.org/wiki/BMW_5_Series_(E39)
...the 2002 model is quoted by Consumer Reports as being "The Best Car They Had Ever Reviewed"
Service maintenance and logs are done properly and completely.
Enquiries are welcome via PM or the link in my Sig below
