Interestingly, most of the C8 coupes I see at car shows have their targa top off and stored in the trunk... Which, as we know, means the profile looks quite similar to the HTC look when the top is open.
For me, seeing the engine is "part of the discussion" AFTER admiring the initial profile.
With my C7, at car shows, I remove the targa top and store it in the trunk - which often surprises people that it will fit there!
I wouldn't mess with the C8 HTC engine cover and risk that there would be damage that definitely would not be covered by the warranty.
Just saying...
