Currently pay $1104 for a 6 month policy with Geico covering my 2012 Mustang and my wife's 2016 Jeep Cherokee. I just plugged in a random Model 3 VIN into the Geico website to get a better idea of what I'll be paying and it's not too bad. I put the Model 3 in the quote as replacing my Mustang and put a $500 deductible for comprehensive and $750 deductible for collision. Only increased the 6 month premium by $204.50 which comes up to about $34 more a month. Not too bad, especially for NJ, but I'm still going to shop around.
