Hot Wheels VW SP2 and Tyrrell P34 six-wheeled F1 car

Was at Target yesterday and found these.  At $0.97 each, I had to get them.  These have to be the most obscure real cars in Hot Wheels' current line-up.  My question is: Hot Wheels cars were selling for $0.99 30 years ago.  How can they be even cheaper now?
