Why are models of cars so pricey?

I was out at the hobby lobby yesterday and I seen some weird pschycedelic re-issue of the AMT 70 pro-street super bee
(come to think of it, I was asked for some feedback once by an automated email from round two and this is the one kit I wanted to see re-issued)

i was really excited about this one because it is THE go to kit for mopar prostreet parts the chassis and drivetrain swap into charger, challengers and late model cudas no problem and it is what i used to finally give roscoe a fighting change to catch them duke boys







this has got to be the only kit i stock up on
