The 1967 Cadillac Eldorado was heavily redesigned, creating a much slicker version of a luxury car. Notice the headlights? No, because they were hidden behind vacuum-operated doors. The Custom Eldorado made the inaugural Hot Wheels lineup in 1968, and now returns— — in its first release since 1971! — in the HWC Original 16 series.

This edition features an opening hood, a Spectraflame magenta finish with matte black roof, and Neo-Classics Redline wheels. More specs and pics here.
