I'm not sure that it's the best,but it would be low risk to anyone considering aft-body streamlining.
Here are a few which Rolf Buchheim and his associates tested at 1/5-scale at Volkswagen,including their plan-view,along with their coefficients of aerodynamic drag.
The 1922 Wolfgang Klemperer body
http://i1271.photobucket.com/albums/...ntitled1_6.jpg
The 1981 'Drop' body
http://i1271.photobucket.com/albums/...ntitled2_6.jpg
The 1981 'Blunt' body
http://i1271.photobucket.com/albums/...ntitled3_6.jpg
The 1981 'Flow' body (truncated tail)
http://i1271.photobucket.com/albums/...ntitled4_6.jpg
The 1981 'Flow' body (full body)
http://i1271.photobucket.com/albums/...ntitled5_6.jpg
They also tested the 1937 AVA G'o'ttengen Schl'o'r pilbug car
@ 1/5-scale it was Cd 0.15 with a smooth belly
@ 1:1 scale it was Cd 0.158 with a smooth belly
@ 1:1 scale it was Cd 0.186 with a 'standard' underbody

I don't have its plan-view scanned yet.Sorry.
--------------------------------------------------------------------------
With 'features' drag,all the models would have a little higher drag (0.008 in the case of the Pilbug car).
*Adding mirrors might add in the range of 0.015 (as with the Ford FUSION LSR car).

The 'Template' suggests that the Insight's roofline is a tiny bit too aggressive,and prone to separation.
The smoke flow image from HONDA also suggests the same thing.

NOTE: If the car is not ballasted,with weight in the front seats,its body inclination may not represent what it will be when 'occupied' by the driver and passenger.If so,the flow would be more favorable.We'd need to get one in the wind tunnel ourselves,and check this.
