StateFarm since I was 16. At 18 under my parents plan, the GTO was $2200 a year. With the age of the car and my age, it was down to $1400ish at 21. When I went on my own insurance at 22, it was $2000 for my GTO and '05 Saabaru. Now since I use State Farm for my house too it's $1800 with the GTO an WRX.
