Because lots of people on Facebook actually complained that the new RAV4 looks rugged and they want to get the pretty previous gen before it’s gone.
My co-worker is one of those people. She wants to replace her 11 year old Escape, so I convinced her a Rav4 would be a good idea. Except she doesn't like the new ones - mostly the interior. She doesn't like the way the center stack closes in around the driver. She much prefers the openness of the previous gen.
I told her months ago that she'd better make her move if she's serious about a previous gen Rav4, because they won't last forever, and she only likes to buy new, not used. So far she hasn't listened to me.
