Last weekend I spent considerable time buying and renewing policies with NRMA insurance.
The rep told me you would be surprised just how many bikes and trailers sold through Ebay and gumtreee
as parts or unregistered projects,,,eventually resurface as stolen when the new owner project/builder unwittingly goes to Register them.
Reminds me of the pain that Lyle on here felt when his ultra smick Frontera went missing.
Same thing they came into his garage to take it.
He eventually found it only just around the corner.
hope you find the culprits,,good luck.
