Hassle at the Border in a RHD car

[KenInOntario]

I was planning on driving my RHD Tuscan down to the states in July for the Brickyard weekend at Indianapolis, reckon it will be cool to cruise through town in it over the weekend.

What's the consensus on crossing the border, I read so many horror stories of the US Immigration giving everyone a hard time, as they assume you are selling it for some reason, and make you waste hours of time sitting there.

Worth the hassle, or just take the daily driver to avoid all the rigmarole
