My Geico went from $610 for my S85 and 2009 Hyundai Genesis for both, for 6 months to $1,625!!!
Holy Sh**!
Fortunately, premiums were NOT due to go up until June and I crashed it on April fools day! (No joke) totalled.
Now my premiums are $450 for just the Genesis. Woo hoo. I'm saving massive money while waiting for the bigger battery, and inside upgrade that I believe will come out with the SUV. And then I will switch if premiums are still high.
Keep in mind, just saying you will shop around or drop them often works. My first S85 and Genesis estimate from Geico was about $1,300, then within minutes, it dropped to $610 purely when they "reconsidered" after hearing about Progressives quote.
The new $1,625 price hike came after they reevaluated insuring a Model S, but the rep was not specific if that was cost of fixing them, or if they just didn't have enough info on the Model S in their system in the first place. Personally I was shocked my S85 and Genesis were only about $100 a month combined (at first).
