I have a 2016 Volt and am considering a 2019 Bolt or Volt, but am curious as to the state of the federal rebate. This will determine whether I buy or lease, potentially. I know the federal rebate is expiring, but how can I best be assured to buy while the full rebate is still active? I don't want to buy, sign everything, then find the rebate just ended (I know it initially gets decreased). How can I avoid this? Surely it's not just 'buy and then hope for the best,' right? I don't want to buy and then be told that the full rebates 'just' ended. Thoughts?
