I did not say my cars do not go on display. They often do, and are appreciated, as you say. It's just the 'concours' type of shows that I don't go in for. Everyone who brings that 'special' car out is a winner in my book. A bit of patina is fine...
I've found 'poly' bushes don't have the same characteristics as rubber. They are 'harsher', and tend to deteriorate rather quickly too.
OK for race cars, etc, if they are replaced regularly...
