Really depends on how old you are, and what your driving record is, as well as what state you're in. www.geico.com , give yourself a run through there on a 2008 Mustang GT. I'd expect similar rates for the Camaro. 100$ isn't bad at all, to be honest. I'm 19, turning 20, and my insurance is around 325 for my Monte Carlo SS. I expect the Camaro to come in around 400-410, for me.
I'd switch insurance companies then. I've never been asked what color my car has been. I've used Progressive, Nationwide and I'm currently with Erie. I've received quotes from Geico, State Farm, Allstate, etc and I was never asked about color.Wanna bet? My Camaro was red. The blue SS I looked at was a more expensive vehicle but got quoted at 305 from the same company.
