To build a model of my Demon, I will mix two kits :
The 71 Duster
And the 71 Demon
The Demon for the upper body and the round chrome mirrors (the Duster has Rallye mirrors).
The Duster for the interior and the underneath (really better made and more realistic) and for the standard steering wheel (the Demon has a tuff)
