I used Geico when I lived in DC three years ago. What stands out to me as their best asset is their customer service and their speed. I had lived abroad for 5 years and had not had insurance in the US for that time period. I had a great driving record and getting insured with Geico was super easy and the customer service was great. The turn around time was a matter of days and their staff were very friendly. I definitely recommend using them!
