Unpleasant experiences can undoubtedly bias you against a company. For myself, though, Costello has been great. On advice from others, I got quotes from two other companies when I insured my LS8 (experimental A/W) three years ago. Costello offered by far the lowest cost policy. And when I factored in their annual lowering deductible and their renter's coverage, it got even better. I'm definitely a fan of Costello, but maybe you being "forced" to change insurance companies will turn out to be a good thing...
