Magazines

The only magazines I read with frequency are either about cars or sports.

I read every issue of Car and Driver. I like the fact they test drive and report on all the new cars before they hit the street. The writers are experts and know their stuff when it comes to cars. They give the specs on the engine as well as  other information like mpg, transmission specs, top speed and report on the overall drive and ride of the car.

When possible, they have pictures of the cars they are reporting on. This is not always possible if the car is not available for sale by the time the magazine hits the streets. 

The advertizing in Car and Driver is obviously relevant and centered on the automobile industry. If they are writing an article on a high performance sports car, you will often find advertizing for high performance tires and accessories located near the article. This makes sense since the article will be read by people that are interested in this type of vehicle and therefore will be interested in the products that are being advertized there as well. It would not make sensee to write an article on the 2012 Lamborghini Aventador that costs nearly $400,00, and then put an add for high mileage engine oil in the middle of the artical. (Although the Aventador is often the 4th or 5th car for its owner and they may have a high mileage slug setting somewhere behind the garage!)
In my opion, the types of advertizing and its placement is as important as the articles themselves and Car and Drive does a very good job
