What is “overall length”:

1. The general length of the vehicle, from the rear bumper until the center of the front wheel.
2. The distance between the front and rear edges of the chassis.
3. Correct answer: The distance between the vehicle’s most frontal point and the vehicle’s rear point.
4. The distance between the center of the most rear axle and the center of the most frontal axle.

WhyOverall length is the whole vehicle from its frontmost point to its rearmost point, bumpers and anything that sticks out included. The distance between the axles is the wheelbase; do not confuse the two.
