We have a local guy here, in his 80's who bought wing cars when they were new. He has a total of five, all 440-6pack cars except for one and it's a hemi. He drives two of his wing cars in the winter even when there's snow on the ground and yes, he puts chains on them.
At one time he got a DUI in one of his wing cars. They installed one of those interlocks in his yellow car Superbird. Probably had the only wing car in existance with an interlock.
