How much kilometers to buy Calibra ?!

Hello Opel friends, had perhaps thought of getting me a Calibra because the car has always fascinated me, but did not have such a big budget should cost so 1000-2000 Euro since all the mostly new TÜV but already 130,000 – 190,000 kilometers down, until how much kilometers should one buy a Calibra in your opinion? I am talking about predominantly 2.0i machines so 116 HP. The standard version. LG
