I was a long time Ryno customer until a year ago when a claim I made was handled very badly, for example trying to BS me with the provisions of the coverage (trying to tell me I didnt have choice of repairer when I did), not returning calls, slow processing time, and having to provide the same info multiple times (they were running two separate files on the same claim at the same time and the one person handling both didn't make the connection - no joke) and even BS'ing when I asked them whether the claims department was in-house outsourced - they said it was in-house, but I eventually found out that their underwriters made them outsource their claims handling to an external mob.
As a footnote, I offered feedback to their head office in QLD throughout the process, and was advised multiple times management would call back, and the staff even freely said they have been getting lots of complains about claims and 'management is very interested in this'. I never got a return call (evidently not giving a #### about negative customer experiences) and after my car was fixed and hire car was reimbursed, I walked.
No idea if their service still sucks (after many years of being fantastic), but the above is my experience.
I looked at NRMA classic, however the have (had?) dumb rule of not being covered if you take the car into 'a major shopping center'. They could not define what a major shopping center was, and told me this would be decided at claim time. I told them there was no way I was going to be wondering if I were covered should I take my car into a shopping center carpark because there is everything from a small suburban shopping center, right up to a large stockland and several in between near me. In fairness, I was not going to be taking a classic car into a shopping centre very often, if ever, but the cloud of not being covered would hang if I ever did.
After all of that, and quite ironically, I went to Shannons and am still there despite having sold my Mercedes (my daily is still insured there).
