- This one reminds us of the Big Bad Wolf dressed up in Granny's nightgown... a 425 HP 426 Hemi V8 under the hood of a 1966 Plymouth Belvedere II convertible wearing color code 661 Metallic Mauve. Yeah, it's pink. And yeah, it's a baaad machine! Plymouth made 10 '66 Belvedere II Hemi drop-tops, 6 automatics, and only one in this color, making this one of the rarest Mopars in the Brothers Collection. It's been perfectly restored, but it still features its original driveline. And because it's a 1 of 1, it's been restored to it's original Metallic Mauve. Would it be more fun in black or red? Who knows, but we wouldn't turn it down!
