I didn’t really choose any specific deductibles when I got my insurance through Geico, I’ll share what I have and the cost (per car):
Uninsured Motorist Bodily Injury
Current Limit: $100,000/$300,000
$18.20
Uninsured Motorist Property Damage
Current Limit: $50,000
Current Deductible: $250 Ded.
$2.90
It’s the same price across all my vehicles/drivers. I pay 6 months of coverage in 4 monthly payments, so that’s about $80 per car for 6 months of coverage. Seems worth it to me.
