Insurance payments for teenage boys are INSANE. $100-150 is the usual but my buddy is paying literally $300 a month on a year 200X Tahoe that he bought for $700 and fixed himself. Its the cheapest option on his families insurance and his parents won't let him switch.
Yup, when I was 18-23 I was the primary driver of our car, but we put the insurance and name under my gf (now wife) and it was half the cost if I had gotten the insurance instead.
