I’ve embarked on a project to build a number of the alternates to 5867 “Super Speedster”. I’m starting with the models from a 2013 book called “The LEGO Build-It Book, Vol. 1: Amazing Vehicles“. This contains the instructions for a ten different vehicles that can be built from the same parts as the Super Speedster set.
The first model is the “Off-Roader” which has some design echoes of the classic Jeep.
