Ben,

It is a fairly easy DIY and gets even a lot easier when you have the tools to remove the fan and radiator/ventilation tunnel...
If the coolant looks clean, you don't need to renew it (I left my 375.000km coolant on after I changed the thermostat O-ring a few weeks back; it was as clean and clear as new).

I have send you the license plate frame and it should probably arrive somewhere at the end of next of next week or the beginning of the week there after. I will mail you about that.

greetingz,
