I have had a subscription to C&D since I was 15, so that's 34 years now. It was always my favorite because of the writing, irreverent, risky at times, covering topics and vehicles no one else would. I was a big fan of Brock Yates and Csaba Csere and the whole crew back then. My favorite articles were always the on-offs in the back, like the triple-threat Firebird from Keith Black or the Lingenfelter Tahoe, but I just love cars in general, so I still have a subscription. I tried going digital, but reading car magazines is so ingrained in my life, I didn't enjoy them on the iPad as much. (books are a different story, 100% iPad now)
I originally subscribed to Motor Trend and Road and Track because I loved cars. While the writing wasn't as good, they always had something interesting for a car nut like me. Today, I find that Motor Trend is more interesting than C&D and R&T mostly because of Lieberman and Pobst. (Pobst is worth the subscription alone.) I keep my subscriptions because they are cheap and I still prefer printed car magazines to digital. I'm also trying out Motor Trend TV. The jury is out but, I loved the Best Drivers Car coverage.
I loved Automobile for Jean Lindamood, but she is gone and the mag is owned by Motor Trend, so you see a lot of duplicate coverage. I still subscribe because I can generally read more than 4 magazines in a month depending on my schedule and fiber intake. Maybe I keep the subscription because it's a habit, but I do still read it.
I have had GRM for, I dunno, 15 years or more? I originally subscribed because it had more low-cost coverage that was relevant to me. I don't think the magazine has changed, I just haven't kept up. I mean, had my life stayed on track I would be working on a similar Z06 project and be very interested in GRM! A lot of people my age transitioned to hillclimbs and track days, so I understand where GRM is at. Still, as an avid autocrosser who drives the cheapest way to get into the sport in a new car and still dominate your class, you'd think there would be more coverage for me. And now that the MFGs are giving you press cars to sample, why don't we have a lap board for them? All cars should be sent through the same autocross course with the same driver to set a time. Food for thought.
And while I admit that I don't read it cover to cover, I do find interesting things every issue of GRM. The writing is conversational, I never have to Google any of the obscure references, and they ask the questions about cars that I would ask. Reading GRM is like talking to my car buddies every month. (which reminds me, a monthly live video from your local bar or the garage, with a few readers, sitting around, drinking a beer, talking cars, killer content right there.) So yeah, I do still enjoy and want the printed magazine, but honestly, because they are not "the man" and they do so much to support the car community, I'd keep my subscription if it were blank.
