I've been subscribing to Autosport for about 5 years now, and buying it regularly before then. The reason I've stuck with it is that their coverage of motorsport in all its forms is second to none. Other motorsport magazines go for the glamour of F1, but ignore everything else. Autosport covers all the main championships worldwide, and the vast majority of the UK club scene too.

Its also got the best range of articles, from the driver columns to the excellent Fifth column, written by Nigel Roebuck. Add in the articles by some of the most distinguished motorsport writers and its pretty hard to beat. A subscription saves you a fair amount too.
