When i was looking for a radiator for the Miata I had to be careful to get what I wanted.
Getting a radiator for an NA Miata is simple. Getting one specifically for a manual transmission is a little more difficult because the bulk of NA Miata radiators are dual purpose. They contain a cooler for an automatic transmission. To use said dual purpose radiators one simply plugs the transmission cooler inlet and outlet. It's a simple task.
Still, I hold with something that says that things that are designed to do two things don't do either thing as well as something designed to do one thing. I wanted a manual only radiator which I did find. It wasn't too hard.
Of course the minute you go looking for something ads for it pop up everywhere. Unfortunately they don't stop when you get what purchase were looking for. I'm still getting ads for Miata radiators (most of which are dual purpose but at least they are usable.)
Still, what makes no sense at all in advertising is when the ads start trying to peddle me things like a radiator for a Honda Accord or an F-150 pickup or other cars I don't own.
I'm not too upset over the advertising because that's what makes the internet free. Still it is somewhat mildly annoying to get advertising for things you have no earthly need for.
One time I snooped into a Turbo conversion for a Miata out of sheer simple curiosity and wound up getting ads for turbo kits for several weeks.
I would imagine that if some guy orders a sexy outfit for his SO he's going to start getting flooded with ads for sexy outfits. In fact if he chose one of certain outfits he's probably get bombarded with ads for whips and chains.
Try explaining that one to her if she looks over your shoulder when you're on line. (Maybe she'd be interested. Who knows?)
Oh well.
Still, I think that over time advertisers will figure it out.
