Yes, if the car that you import has some modifacations then the workshop that is complying your car will have to replace the mods with stock parts for it to be able to get complied. Seems like your fairly new to importing a car, my advice is to do alot of research first it would make your first importing process alot more easier. As the others have said, you have to be patient dont jump on the first one that comes across cause you dont want to be dissapointed. Took me 3 months before I found mine, just ask if you have anymore Qs.
