I've noticed that in most TR pics the engine bays are the same color as the car's exterior.
Makes sense - it's all sprayed at the same time.
But in a few pics the bay is a "dull gray" - like primer.
Is there a useful purpose in *not* repainting the bay when repainting the car (other than painting without pulling the engine)?
Or a reason for painting the bay a different color than the rest of the car?
