He means "magazine racing" but he's gay and says check book instead.

I thought he was giving you crap for paying someone else to do the work.

What's magazine racing?

I agree.

I am going to take a shot at this one and say it is someone who has not idea what they are doing on a car and pay someone to make them the baddest and fastest car and never actually race it or put it through its paces. thus gracing the covers of magazines as a "show" car rather than a real work weekend warrior.
