this might be the best magazine prices I've seen for subscribing to Muscle Car Review and Hot Rod Delux, at least, in one place

You can compare with other subscription renewals I've posted http://justacarguy.blogspot.com/search/label/subscription%20renewal  and see that it's the same price for Hot Rod Deluxe (a very good magazine) and a bit better than 1/2 off the previous cost for Muscle Car Reveiw (another very good magazine) and Mopar Muscle is typically ridiculously priced at 30 a year, but for 15, that is a good price.
