4. Windshield and Grille
For the windshield, draw a rectangle. Sketch two slanted lines with circles on one end and double lines on the other for the windshield wipers. Form the front grille by placing a square inside of a slightly larger square. Add several upright lines inside the smaller square to complete the grille.
On both sides of the grille, draw a circle within another circle for the headlights. Place four small rectangles on the front bumper for parking lights and turn signals. Use four curved lines as straps around the gas tank.
