Strongly recommend that you add some tax rate(s) to your calculators not to throw off people who don’t know how to use calculator and expect no more than 10% bump and then be hit with about double that and about extra grand on DAS.
FYI, one of your CA competitors took a lot of heat for that and now they show two tax rates (i.e. 7.5 and 9.5%) to have much more transparency since CA taxing incentives makes a big difference on EVs.
