Our State Farm 6-month insurance premium for our Tesla Model S went from $726 in March 2013 (with two cars insured for $450 + $726 = $1176) to $1061 in September with only one car (the Tesla, the second car was sold in May).
The drivers did not change and there was no new data from DMV or others, the coverage did not change, the Tesla did not change. This seems to be a number game with their single car insurance discount that brings the total cost of the premium for two cars to roughly the same amount as for one car. It does not make sense from the customer point of view.
Would someone have any better option? We would also transfer our home coverage and umbrella coverage.
