Just a little word of warning.
When I got my nice new Iceberg Silver Mk2 172 back in May 2002, 13 days later some idiot on a petrol forecourt drove into the back of me. Gutted.
Not much damage, rear bumber needed replacing and some small repair required underneath. When the repair shop (recommended by my insurer, DirectLine) told me the car was ready, the bumper was a different colour - iceberg silver, but not MY iceberg silver. They had ordered the correct paint/batch variant, but it still didnt match. Eventually after some arguing, they agreed to get it colour matched by manufacturer, so they sent off my petrol flap to ICI. Turns out ICI no longer make the original Iceberg, but a "new" version of it instead!!!! Considering my car was only 13 days old, seems a bit mean to discontinue the paint.
Incidentally, the paint shop fella said paint from the same batch may still not match anyway, depends on how long its stored etc.
Good luck.
