falling car prices and insurance

I've been reading in the newspaper about how much the price of expensive gas guzzling cars has dropped since the gas prices have sky rocketed, and have been wondering how this will affect car insurance rates. For a lot of people, this is a great time to buy a vehicle, although buying a gas guzzler is not good for any time of the year or economic situation, I feel. Insurance rates usually stay quite competitive, especially if you search online, where it is possible to get some really good rates. I wish I had done that when i bought my last car, when I ended up getting insured by the agent tied up with the car dealer, often the most expensive of the lot.
