I did a search, and saw many people complaining they had problems getting their tax credits. Most of those were a couple years back. So here:
1. Is IRS still denying credits when everything is in order and causing hassle and anxiety?
2. Is federal credit limited to what your actual tax is (like if your tax is $5000, you can't get full $7500)?
3. Is there a way to find out if the federal credit has been claimed/redeemed on a particular car? There is a local seller (private) who says I can get the federal credit because he didn't claim it I would hate to be out of money and then have to drag him guy to court (or police).
