When working with flat polys I used mainly the first running demo of Harley and some particular case of the first car demo in Le Mans 24. The latter It's not perfect, see below:

look to the rear spoiler, on the original hw the highlight suddenly disappears at some angles instead of fading out like in my solution. Also the front one is darker on original hw and while being flat is marked as smooth poly so inherits the same parameters as the rest of the car.

Harley's surrounding buildings:

Please note that on original hw the flat poly highlight is brighter if the poly is parallel to the camera plane (i.e. it's face normal perpendicular to it) and fades out a little when changing angle. I tried to emulate that effect with the help of the Blinn-Phong solution. Check Abe's Harley direct capture as reference.
