My sister's attitude is "if it's that important or desirable, then someone has it on the internet." That's true to a point. Magazines with road tests of certain desirable cars in them--Corvettes, Ferraris, Porsches, Cobras, Mustangs, Hemi Mopars---but magazines chock full of tests on lesser cars? Not so much...
Personally, I'm split between the two camps. I like most of the cars in the first camp, but I'm interested in the second group, too. I'd rather have a mag with a five-page test of a, say, Oldsmobile Cutlass Cruiser wagon, than one with a five-page driving impression of a Porsche 911 Turbo.

I've been on a tear recently, hitting antique malls. Old '70s issues of Pickup Van & 4wd aren't worth $10 each, in recent trips, in my mind, But maybe if they were $5 each...

I spent 35+ years acquiring magazines, from the basic four (Car & Driver, Road & Track, Motor Trend, Hot Rod) all the way to obscure East Coast 'street racer' mags (Cars Illustrated, Drag Strip, etc.) At my peak, I was subscribing to, IIRC, eight different mags(the basic 4, plus Automobile, Special Interest Autos, Super Ford,...and some publication called Scale Auto Enthusiast...LOL). Today, it's zero subs. Heck, the surviving mags have gone to a bi-monthly or quarterly publishing schedule.

I noticed this week it is getting harder to find that obscure car mag these days. Before Drag Racer went online or subscriber only, I used to find it ONLY at a small chain supermarket near my apartment. And this week, a trip to Books-a-Million in Grapevine revealed that chain stopped carrying magazines entirely.

The internet is not the 'home' of older car articles like my sister says it is. I was poking around the net a few years ago, searching for an old comparison test of the Cadillac, Lincoln, and Imperial. Found it on an Imperial club website...but it was more of a retyped transcript o9f the original test--there were NO photos from the test, on the website.
On the other hand, I found a Car Life test I've been looking for for years online. Not only that, but it was set up where I could just print off the pdf pages to my heart's content.

At old car swap meets, I'm seeing fewer and fewer vendors who specialize in selling/buying old car mags. At the pate swap meet this year, there was one guy selling his collection of Pontiac Enthusiast and High-Performance Pontiac, and there was another vendor with a small stash of The Bulb Horn and Antique Automobile...from the 1950s! Wow,,,antique antique car magazines.

Have to search my heart, to see if it worth tracking down every issue of Auto Tech magazine (12-issue run, all in 1989), or maybe replace my collection of Speed and Supercar (east coast street racing mag)
