How to Import a personal sidecar / motorbike? (Santiago de Chile)

Hello

I am fresh off the plane so apologies if i've posted to the wrong forum!

I am in the process of importing a sidecar into Santiago (form London). It would be great to get some advice from anyone who has already gone through the process of importing their own car / bike for personal use
It seems quite confusing and from what I can find online I need to hire the services of a "Customs Broker Service"

Many Thanks
Chris
