im from the U.S. so i know nothing about the fuel, or importing requirements. however, i know very much about the car. you say it has a new motor? meaning it is not an original ls6 454 chevelle. how much are you looking at paying for this car. if it's not the original ls6, then it wont be worth it. but if it is and you can pick it up for less then 40k depending on overall condition, i would jump all over it
