around 10 years ago, car modding was in full force in the uk, 5 years ago you would still see modded cars but now you rarely see any save for the odd modded corsa belonging to questionable people.
Its not just in the UK however, in japan the car culture there has been disappearing as well and you dont see as much modded cars anymore (based on info from car sites + friends who live and been to japan).
so yh, feel free to discuss about it, why you think its happened, whether you mod cars, own one, etc.
