We started by identifying Texas’s five biggest auto insurers by market share, and compared their financial strength, coverage options, and customer service, using methodology similar to our review on nationwide providers. Then, we checked J.D. Power and Consumer Reports to see how each company’s customers scored them, both overall and on their claims experiences. Next, we looked at the Texas Department of Insurance’s “Complaint Index” for each company — a measure of how consumer complaints filed against them compare to the state average. And finally we collected quotes for six hypothetical drivers, taking note of each company’s available endorsements and discounts.
