These generic figures aren't very helpful, tbh. Need to share coverages, credit score, driving history, etc.
I'll contribute in hopes it's helpful for someone in my area (Boston):
Age/Sex: early 30s male
Credit / Driving History: Both excellent/perfect
Cars: 2 (08 Jetta, 18 Tesla 3)
Other Discounts: Life Policy and Home Policy (multiline), E-discount, autopay discount, + car specific discounts for safety features
---$250/$500 (for each bodily liability to others, bodily coverage for self from uninsured motorist, and bodliy coverage for self from underinsured motorist)
---$250k property damage liability
---$1k deductible for collision and comprehensive
---no towing, no rental car
Tesla 3 was $1239/yr, but also reduced my Jetta cost by $65. Net increase about $1175 which doesn't seem bad given my high coverages.
