It has to do with intent ... you cannot buy the car knowing you will immediately resell it like inventory on a used car lot. Eventually everyone will sell their personal vehicles which is normal but for the credit you must buy the car in your personal name and intend to use it personally and not resell it shortly after purchase to make a profit. FYI ... the cost basis must be reduced by the credit taken so if you do sell it shortly after purchase you very well could have a taxable capital gain.
