Well, I get a LOT of car mags, but I'll only list the ones no-one else has talked about...

Lowrider
Lowrider Euro
HCI
Import Tuner
Sport Compact Car (yeah, mentioned once)
Truckin'
Mini Truckin' (I think that's it)
and a whole lot more...
I usually browse thru 'em on the crapper, and use em to guage where the industry is at, and where its going. (Its part of my life, so I gotta keep up on what "the kids" are reading.) Its amazing to me some of the crap these magazines consider content, however, as most of them suck unless you like to only look at pictures.
