Can my insurance company charge me an additional 130 dollars for adding another car with just liability insurance?
It's very likely that they can. Many factors go into setting
prices on policies. If anything about your credit or driving record
changed, or even if your company simply does not want new business
in your area or does not want to insure certain groups of drivers,
your rate could increase. If you want to switch companies, try an
independent insurance website to compare car insurance rates from
multiple companies at the same time.
