Fully assembled (6-wide) Modified SPEED CHAMPIONS McLaren 720S (75880) with the GT Road Warrior Edition Conversion Kit applied.  Inspired by @djxtrodinaire GT Edition and featuring Chrome Rims by @ChromeBlockCity.  Only 3 of these cars built and one remains part of my personal collection.  Orange exterior with Black accents and Black interior.  This is my favourite Modified SPEED CHAMPIONS LEGO Car.  Includes:  Marcus Firegone Custom Designed Black Chrome Dash, Chrome Rims, McLaren Designer Minifig, Helmet, and extra LEGO to make the side panels all orange if you prefer.  Cost:  $47 for discontinued set, $14 for 38 extra LEGO parts including Custom Black Chrome Dash, $16 Chrome Rims, $15 Build Design Fee, less $2 rebate for leftover parts.
