Unfortunately, about everything, but for starters, it never went through Customs, we just found out, and doesn't meet EPA emission standards to begin with. Sadly, we're just going to have to return to the Mexican Nationals who sold it to us in California. I don't think they knew it couldn't be registered and we certainly didn't! Anyway, thanks for trying to help, but the EPA has already called me on it....Too bad. It is an awesome car that outperforms and out-looks anything in the USA today. =[
