A(sq.ft) = 0.84 (Height" Width")/(144-sq.in/sq.ft)

A = 0.84(49.6"65.6")/144 = 18.98(sq.ft)

CdA = ACd ...and its Cd is about 0.35-0.40

Thanks Ole Tele man!
I also used this calculator which was pretty cool IMO.
Vehicle aerodynamics
I got .35 from it and other online specs, it was pretty hard to find info about my car.
I also got this from it :
CD = 0.360; CDA = 8.11 ft; CLA = 7.22 ft
