We really appreciate your help and input.
We made the mistake of freaking when our current insurance company told us that the rate would be some 2.5x what it is now to add the H3. The dealer had said there would be no difference in price, so we were shocked. Things were happening fast, so we backed out for a bit.
We've now called other insurance companies that aren't Hummer Haters and the rate will be fine
The vehicle hasn't arrived at the dealership yet, so we should still be able to get back into it since the price seems fair...
Thanks again.
