Will I get the tax incentive if I sell the vehicle before the end of the year?

Dealers in effect do this all the time when they lease vehicles in effect. I say you’ll be fine if you have proof you purchased the vehicles during the year. When you actually file shouldn’t matter.

 

....The vehicle should not be purchased for the sole purpose of reselling it.

I think you'll be OK but I would get confirmation that there's no limit for individuals or families.

You may want to wait a bit and see what happens in the "three lies for the price of one" BBB plan.
There might be significant changes in future rebates that might make you wish that you had waited a bit - but OTOH if you're buying new cars all the time it probably won't make much of a diff to you personally.

Good Luck!

This has come up many times. In short, you can do it, but be aware that IRS has the last say on the "recapture" of the credit.

Not exactly. The car on the lot is owned by a bank. When the dealer sells it to the lessor (bank or the auto maker's finance arm) then that first buyer gets the tax credit. The car on the lot has a manufacturer's certificate of origin or statement of origin serving as the title document. The first owner to get a state title (the lessor bank or car buyer) gets the credit.

 

You can. You will owe short term capital gains tax (your income tax rate) on the amount of profit generated by selling the car, and your $4,502 tax credit reduces your cost basis dollar for dollar.
