Volks World This is my favorite aircooled magazine, straight from Great Britain. Big, glossy pages with features, tech articles, and more.
VW Trends Another great magazine that just keeps getting better, VW Trends has multi-part restoration features, owner/vehicle features and more. The website also has just added a forums section.
Hot VWs Hot VWs completes the VW aircooled mag trifecta, with an emphasis on power and speed. The ads are also catered more toward the performance crowd, rather than the restoration aficianado. Not much on the website, but you can get backissues there.
