Is There A Peugeot Service Near Ataköy?

I can be an active member depending on the recent situation ... :)

My question is, as the title suggests, I am looking for a reliable service you know in or near Istanbul Ataköy . I live in Ankara and found a car in Istanbul. 406 . Is there a Peugeot service that you can check, know or compu-test this vehicle? I plan to be in Istanbul on Monday , 08.01.2014 . Are there any friends to help?

Thanks for your answers in advance.
