Wow, I am 27 and because my dad has so many cars insured on his plan I just elected to stay on his plan, it works out the best for everyone. I am paying $207/month for full coverage on the VX and the RX-8 (in Houston). $104/month per car. If I were on my own plan (not on my dad's plan) it would be $300 a month. We are with Geico and have 7 cars insured on my dad's plan now (big family).
