not my expereince with Just Cars at all. I made a big claim, on a modified import with no isues
Shannons for me is $800/year with 500 excess for cover of 30k on a 33GTST...so as you can imagine...I'm pretty happy with them. My rate has never increased and infact last renewal i uped the coverage from 25 to 30k which they did no issues. Great guys IMO.
However I tick all the boxes. postcode, locked private garage, nweekend use only, CAMs car club member, 2 car policy with them and 30yo. These factors make a big difference.
