Walaikum Assalam Sir, although i live in Chakwal area but i own a santro plus and i can give you an idea about it that its maintenance, fuel, parts are expensive compared to mehran plus its an old efi car which can give you different issues anytime and lastly its resale value is less so my sincere advice is that only if you find a really well maintained first, second owner car then only think about it otherwise better to stay with mehran
