It's a GREAT magazine. I've been subscribed for at least 10 years now. The people involved are warm hearted, real car people that understand what makes these lovely old machines tick. There are about as many articles on mercedes as there are corvairs, hudsons and Hispano-Susas. Heck, I wouldn't have know one wit about the HS's w/o reading Skinned Knuckles.
If you like getting your hands dirty, this is definitely the thing to read. It's short, usually about 50 pages (lots of pictures), clearly written, and always worth the time.
