I back this statement. I never pull shady shit at customs because growing up I was always taught not to do so.
My Dad had his 1957 Ford Fairlane seized back in the day for not declaring some clothes he bought in the States. He had to get a ride back home then come up with the money to BUY BACK HIS CAR AT BLUEBOOK.
