I agree that under the circumstances, you are required to file form 3520. There are no tax consequences, this is a transaction report that the IRS uses to look for money laundering and other things, it almost never rises to the level of further inquires, it's just a report.
Form 3520 is filed separately from your tax return (not with your return) although the filing deadlines are the same. Turbotax does not include this form.

You also technically gave your friend a car worth $26,000. That must also be reported on a gift tax return form 709, although no tax will actually be owed, but the gift musts be reported.

There might be an argument that instead of this being two gifts, you were acting as a purchase agent for your friend, but that might have other, unexpected tax implications that I don't know anything about.
