Wondering about insurance for new muscle

As a 22 year old with no accidents or tickets, I pay $127 a month for my 06 Charger RT. No collision coverage, just basic comprehensive with a real high deductible. This may not seem like a good deal , but when I was considering selling that for an '10 Avenger with a 4 cylinder, that same coverage went up to a whopping $260 a month!! And the Charger stayed put lol.
