My proclivities are toward the traditional wood dash, however I have seen other dashes I thought looked nice. I don’t remember any alternate crash pads that I liked though.
I think something that gives the interior some “classic” elements work best. Engine turned aluminum might meet that but for me it is too reminiscent of much older cars.
I also think that the Europa benefits from more refinement rather less. Just so you don’t think I’m really heading to a “wood only” position, I thought the gun metal dash of a car recently for sale looked nice and and also worked well with other elements done in the same color (bumpers, trim, etc.).
But all those are just my opinions and the person you want to make happy with your car is you.
