I have a couple die-casts on a credenza in my office. One is a 1/18 scale Maisto Porsche Carrera GT (no big deal), the other is an Anson 1/12 scale '98ish Black Dodge Viper RT10. This one is nice; has elasticy seat belts and cushiony seats. Detail is pretty good except for the underside. Here is a similar model, but I paid $80 for mine:
