I'm 23, 1 ticket on my record and I pay $62 a month for full coverage

I just want to note that in some of these posts, where insurance for a new Bonneville was ghastly amounts higher than an older one, like a 93 or something, a lot of that cost is probably for the relative difference in value of the cars, and has little to do with the supercharger option costing more. Also, new cars bought with loans need full coverage, -but were we comparing to full coverage on the older (1993-ish) cars?

Most insurance companies recommend not carrying full coverage after a car'* value depreciates so much. I still have full coverage on my `97 SE, but when I recently checked rates at Geico, the only way they were cheaper than my current insurance (Farmers) was if I dropped from full coverage to liability only on my Bonneville. (And when you figure I could just do the same thing with the insurance I already have, well, then Geico still wasn't lower.)

That said, when I got my `97, there was a slight increase for the supercharged models. Also, at least here in California with my insurance company, they have a surcharge for "excessive horsepower" engines. I think they use a calculation of power -vs- weight, and if the power exceeds a certain amount, they slap you with a higher rate. A Corvette, or a GTO for example, would qualify. Ironically, I read an article recently that said the calculation puts huge SUVs into the most favorable insurance rate category, since their weight is so great. The article was about insurance companies considering hiking rates on gas-guzzlers to penalize them for their hit on the environment. (Not the business they're supposed to be in.)
