I had pre face lift and now have face lift car , i think the early look is nicer and more pure , change it and you will loose value on the car , people will be put off and think its had major font end shunt. My advise is don't bother or you will end up paying twice.
The car is made of fibreglass. With right knowhow/cash you could graft a plastic swan to your car if you so desired. With right piece of bumper I wouldn't have thought it would be too serious a job for someone handy with fibreglass.
