I get Hemmings Muscle Machines, Car Craft, & Muscle Car Review. I have had Hot Rod on & off since 1988. I do miss how the articles used to be in all gear head mags. Now they don't seem to be as diverse. With it seems like most mags being published by one company, each one has a specific subject theme.
I noticed the same thing when a large company called 10 was publishing the majority of the car magazines. GM High Tech, a Mustang Mag, and a bunch more were cancelled. You are right how the company tried to make their mags subject specific. One Mustang Mag was for the old cars, other for the 5.0 and up crowd. Car Craft seems more on the tech/ engine side of things where Hot Rod has more of the rat rods, unique cars. That is all well and good, but over the past 5-7 years I have found issues with few articles or stories I am interested in.
Part of the problem in my case is time itself. I still have all the magazines from the 80's that had Monte Carlo SS articles as well as the new car issues that came every October. I was buying my first new cars, enjoying all the new performance getting better every year, and most, if not all the car magazines I bought then were read cover to cover because I had a new car and many of the tech and repair stories were relevant to me.
I still have a 30 year old car but not much coverage is done nowadays on the cars I really like. It is nice to see the last Car Craft and MCR magazine give kudos to some 80's cars.
The new performance cars are unbelievable and I never thought I would see cars like a Hellcat, COPO Camaros, 1000 hp Shelbys, an electric Tesla going 0-60 in under 3 seconds, and now a new Challenger Demon that might be the fastest car ever produced in America. If you asked me 20 years ago if these cars could exist I'd say you were crazy. Only places those cars existed was in the magazines trying to guess the future. And boy they were way off too! But it was fun to read their guesses and dream about owning one of those futuristic rides.
