Are the cars you sell all allowed in boston? thank you.

I am not sure about Massachusetts. (Boston) you will have to check your State Laws on emissions packages required, But for Example most of the cars listed can not be registered in California because California has an emissions package that is factory installed specifically to sell in California only .. Mass may have something like that, Check with the Mass DMV

Thank you for answer. I already checked Mass DMV but all i found out is about car registration and licensing etc. A list of acceptable cars in Boston where you won't get charge or caught or something like that. But anyway, thank you!
