You can get another $7500 credit from the Feds. $3000 would not be enough for me to give up my Volt.
I replied to this but it seems to have gotten deleted. I need to fit payments within a certain amount per month. The $3,000 got me under that limit. Without that, I will not be under the limit. And while there is some incentive for the $7,500, this does not come off your loan. In other words, if you get the $7,500 back, even if you put it toward your loan, it does not change the loan payments. It might effectively change the term, if you continue to make payments, but it's doesn't help as much as people make it out to help. We also did not physically get the $7,500 -- we applied it to taxes.
Also, while I like the Volt, I'm not enamored with it. I think the control system is way too freaking complex, I HATE having to climb out of the car and get snow off the rear hatch so I can see through it, and it really doesn't save much in the way of operating costs. The one month I actually used the car, I paid $50 in electricity and filled up the gas due to temperature. That's about the same amount I was paying for my VW diesel. In the summer, it would be a more dramatic difference, but in the winter, it's just OK.
The main reason I'd get another Volt is because I have everything for it, snow tires, floor mats, you name it. I'd have to sell all of that.
