Hot Wheels just came out with their 1/24 diecast 458 Spider.
Honestly, while a 458 Speciale or Speciale A would be nice, it's a lame duck compared to the 488 GTB.
If I were a plastic model company, that's the direction I would go (though the LaFerrari XX would be wicked). Would be perfect Revell AG subject to do both GTB and GTS variants (you know there will be a GTS coming after the coupe).
