Of course she's going to say that, she wants to scare you into staying with her company and giving her the business and commission. There's nothing wrong with GEICO, I had them for a few years until I decided to switch back to Progressive, my old insurance, as I got a better deal by doing the family plan with my parents than I did with GEICO. It's obviously a scare tactic.
Car salespeople do the same, when I told my family's Honda salesman that I was tired of their cars that looked too matronly and found a Toyota that was more stylish and sporty, he said I'd be sorry as Toyotas rust within a year or two of owning them and constantly break down. Funny, considering the Camry is one of America's best-selling vehicles and Toyota was the top-selling car company in the U.S. for quite some time. I know plenty of people who have had their Toyotas for 15+ years and still running. Therefore, I ignored his threats, got the Toyota I wanted and kept that Toyota for 4 years until I upgraded to a V6 model of the same vehicle last year, and I had no rust or any issues during those 4 years.
I got a better deal, cheaper maintenance prices, and no more long waits at the dealership for service as Toyota has more dealerships in South Florida than Honda does.
My parents and sister still use him every 3 years when their leases are up, and they like the Hondas, so I guess in the end, it was a win-win even if he lost me as a customer due to the fact they got rid of their sporty lineup. Ignore this woman and do what is best for YOU.
