Ground Hog Day Level 1-32 is solved in two steps with one contraption. Build a solid four box cart with power wheels and the combustion engine. Navigate your vehicle up the hill, through the first tunnel and let gravity pull your vehicle down to the finish line within the time limit. In the second step, we powered our way up the hill and over the first tunnel to collect the star box on the far right. Let gravity do the rest by turning your engine off. Your vehicle should slowly roll backwards towards the finish line.
