Well, it looks like insurance for the Model S will be quite a bit more than the old 2004 Honda Accord (like I didn't expect that). My State Farm agent is quoting almost $80/month. Yikes.
Well, I'm still saving money on operating/ownership cost (compared to a gasoline car), I figure; but this will certainly cut into those savings. We'll see... maybe multi-policy discounts will kick in, in the end.
