There are things to consider when buying auto insurance like the quality of repairs. If a car is repaired with aftermarket parts it's safety rating could be radically altered. Computers have altered the way cars are designed. The Crumple Zones are dependent on the qualities of the body parts. A cheapie repair could leave you at risk. There is also the aggravation factor. I dealt with some super-shitheads with Allstate before, it was maddening... In california every accident I ever had was with an uninsured driver, most of them are minorities and the state has a hard time bearing down on the "poor" and getting them to actually be responsible.. I used to drive really well chosen used cars that would be covered by the small payouts from uninsured motorist policies and get just the cheapest insurance and add uninsured motorist protection and it worked out pretty well. It didn't make sense to me to buy a new car when the state had fixed things so it couldn't really be insured no matter how much coverage I bought. I had a big property and if we totaled a car I'd buy it from the insurance company and part it out from the back yard. I discovered that I had the first right to buy the car for some reason, I think it was California law... I had a full size Chevy that was worth far more in parts than running because people kept that particular car and repaired them forever, small police forces included... That thing was a carcass about a week after I ran the ad.
Mexicans will buy the most mangled, bent up cars and put them on the road. I talked to one guy that straightened frames with a come-along and a tree. I'd never buy those cars, the tires wouldn't wear properly because car frames are measured in millimeters, not by eyeballing it and working a come-along..
