if insurance is an issue, sell your car and get an '11+v6. Putting out 305hp with 280ftlbs at the crank, nothing you can argue about putting a turbo on there. Oh yeah, thats 95 more hp than the 05-09 v6. I had an 07 v6, and my 13 v6 makes a drastic comparison in hp. Insurance is about the same.
I remember before I bought my mustang I got a few quotes on insurance for cars I was interested in. A Toyota Corolla would've been about 30% more, an eclipse was more than double the cost, a Corvette was only about $100 more, the price for the GT was the same as a base model (all based on a 6 month policy)
