SXR, welcome aboard

. Where in Australia are you located?
On your insurance question, take a look at this thread for the Aussie member's insurance experiences:

I have been told by Chrysler HQ here that there is a tow bar engineered for the 300C, so that should not be an issue for you.
GoofyTim has provided the background to where some of the components are sourced however the 300C we get in Australia is actually assembled in Austria.
On dislikes, firstly let me say this car is "ACE". Outstanding value for money, excellent equipment levels, excellent safety (primary and secondary)(5*), excellent performance, outstanding style and presence, outstanding quietness & NVH, excellent build quality (even though some motoring writers have made some criticisms), reasonable fuel economy and finally, only reasonable handling & steering feel. I am sure lowering would improve that.
My wife's car is an Audi which replaced 21 years of Hondas and is the first European car we have owned. What a difference.
My 300C is my first non Aussie car (mainly Holdens), WHAT A DIFFERENCE
