You are right. In theory it would be a high paying niche but isn't. I still make good amount form it because I get a lot of traffic to it, but my main earner is my health site. The cpc is like 4-5 times as much as the automotive site. At least it was until the May crash.
But I do have a couple of private advertisers on the automotive site who pay good money each month so it kind of makes up for the rather lousy CPC.
