Thanks for the replies. I know that the two piece set up was not generally original to the 280, but neither were many of the other things I referenced in the post that I guess I attribute to the original euro delivery of the car. I neglected to mention that the car also originally had no power steering altho I have added it. I am pretty sure that the wheels that came on the car are the originals, in fact the spare has the original continental tire (virtually unused) with the raised rub strip. So, again speculating, my thought is that the car was likely delivered with two piece caps and rings. As to driving habits, I don't race or rally but do love those twisty roads. As has been pointed out I am not obsessed with originality, but cosmetically I like the two piece look. When all is said and done it has been wisely pointed out that the answer really lies in personal preference. Thanks.
