Is an object's weight it's net force?
For example, a car has a net force of 280N. 400N forward and 120N drag.
Is the car's weight 400+120N? Or 280N?
I ask this because I need to use it in the F = M x A equation.
280 = (280 x 9.81) x a.
Is this correct? Am I using the correct weight?

What goes into F=ma for "m" is the MASS of the object, not its weight. And certainly not a force*g.

No, the 280N force is a horizontal vector, pointing the direction the car is facing. The force of gravity points down, and can't be calculated with only the information you've given.
