You think $100/mo for car insurance is expensive? The average car insurance rate is apparently $133, but I personally know it's not very hard to hit more than $100 (even on an older model car) if you want more than liability.
I'm nearly 40 and have been driving for decades. I recently downgraded to liability and it's still $55/mo for myself and my similarly aged significant other.
Definitely! Mine is $500/year for full coverage in the UK.
