Very rare that your typical monthly car mag has a special feature on something old and Japanese...but the latest Autombile mag - Jan 2007 has a nice 2page feature on the 510 as a "Collectible Classic", there is reference to Mr. K, the L series and the 240Z in the article as well.
It also features a great layout and article on the BMW 2002Tii, which is a car that has a special place in my heart.
Worth picking it up!!
This is the cover:
