The sides of the car have the slowest air,and least kinetic energy.Unless the sides converged exactly as the roof,as in a pure streamline half-body,they would not be able to tolerate as much contour as the roof flow.
The drag minimum 3.92:1 contour for 2D flow might be a safe place for us
The MG EX 181 used a plan-taper very much like it and recorded Cd 0.12.
