SEL_69L, respectfully Sir, an old bonnet star may not be a lot of use,
I do not completely understand the particulars of how these work, they have a spring, as I understand it, that holds the star in place.
If you try pushing or moving a star on a brand new Mercedes, or on a car that has just had a brand new star fitted to it, you will understand what I mean, it is very stiff and hard to move at all.
At the other end of the scale, get a 30 year old Mercedes, that at highway speeds the wind will push it out of alignment, and if you adjust it, back to highway speeds again, it will flop over to one side. No doubt caused my countless brainless idiots trying to break it off and steal it. Eventually the mechanism wears out.
The single most annoying thing about driving a Mercedes is a star that is not perfectly aligned, I could tolerate dents, engine smoke, broken electricals, smashed in rear end, groans, but you cannot mess with the star, it has to be perfectly straight and standing to attention at all times.
It is like a battleship without its colours flying high in the wind,
Fit a new star to your car, the shiny new chrome work will give you endless hours of pleasure admiring it as you drive along with the sun shining down upon it.
