I claim the ornamental design for an automobile, as shown and described.
FIG. 1 is a right side view of an automobile, showing my design;
FIG. 2 is an enlarged view of the portion 2 encircled in FIG. 1;
FIG. 3 is a front perspective view of the automobile of FIG. 1;
FIG. 4 is a back perspective view thereof;
FIG. 5 is a front rendering of the claimed region of FIG. 2;
FIG. 6 is a right side perspective view thereof; and,
FIG. 7 is a left side perspective view thereof.
The additional views of the automobile not provided herein do not provide any additional claimed features of the design and thus are not represented. The bold dash-dot-dash broken line circle in FIG. 1 shows the enlarged region encircled in FIG. 2 and forms no part of the claimed design. The remaining broken lines are included for illustrating environmental structure and form no part of the claimed design.
