Another alternative, make a removable cover, paint it black so it won't be noticed
and remove it when you want to show off the car.

I would screen it, though. If you pay for the screening, I can help you install it.-Bob

.......screening also keeps birds from getting sucked down into
the motor when you floor the gas....
