Responses here will not matter unless you find someone with similar demographics, credit history, driving history, etc.
Indeed. There are too many variables at play. Even listing a few of them, as the
@jakebake did in post #5, won't be enough to narrow the field significantly.
You just need to shop around a little. I was getting outrageous quotes too. I ended up at State Farm for less than $100/m Costco was cheap as well.
This is the correct approach. Call a few insurance companies, use their Web sites, or use an agent or Web site that compares rates from several insurance companies. When I did this, I found that rates varied outrageously for me. IIRC, it was something like a 5x factor, although one of those was an outlier on the high end, so it was more like a 3x range for the bulk of the estimates. FWIW, I ended up with Progressive. Based on other discussions on this forum, Progressive seems to have better rates than most insurers for Teslas, so if I had to recommend just one insurer to try, it'd be Progressive. My old insurer, Geico, seems to be hit-or-miss; some people say they get good rates through them, but others say not. For me, it was just over a 2x difference between Progressive and Geico. IIRC,
@RyanT's State Farm is pretty good by most reports, too.
Also, probably a stupid question but if you lease a Tesla you don't get the tax credit do you?
For the US Federal tax credit, no; that goes to whoever owns the car. If you lease, that's Tesla (or whoever they're working with to finance the leasing; I don't know the details of how they're doing it). That said, some finance companies factor the tax credit into the lease calculations, but I don't know how Tesla's doing it. If it is being folded in, the result will be in whatever bottom-line monthly payment you're quoted.
State incentives may be another matter. I have no idea what's available in Arizona or how it works there if Arizona has a state incentive. When I leased a Chevy Volt close to three years ago, the Rhode Island incentive went to the lessee, so I got that. Rhode Island's incentive has since run out of money, so I got nothing when I bought my Model 3 1.5 months ago.
