There are a LOT of things that go into determination of premium, even given similar vehicles. Things like deductible, liability limits, location, driving history, the dreaded ASL (), insurance carrier, and vehicle cost, to name a few.I don’t know didly about insurance but this cost disparity must be related to location.
When I got my quote for adding the GX, my carrier, USAA, said it would be about $89 a month more. In contrast, my 2012 Escape with 200+K miles on it costs me about $71/mo.
