Bundle vehicle insurance with my brother & his wife?

Long story short. I do not have insurance and neither does my brother and his wife. We were hoping to maybe bundle somewhere to save if possible? Located in KS. We have two separate addresses and two vehicles. Both jeep latitudes (2014 &2016) and both financed so needing full coverage. Of course the cheaper the better right now. Don’t want to repeatedly put info in to a million insurances and be harassed by the emails/calls.

Can’t use Progressive, Root or Geico. Liberty quoted $322 already.

Any info of where to look is appreciated!!
