Mustangkauf Tipps, Tricks, Problems, Questions

Hello, I had already put the topic back into the background again from avoidable sense of reason. Of course, the alert has remained in it. A very interesting offer at mobile.de then fixed me again and I could not resist contact. Unfortunately the purchase did not come to a standstill. The car is probably now still in the acquaintance circle, bad luck had. However, with the GT everything fits simply: low mileage: 8,000 km, price far under 35k, warranty extension, perfect understandable history etc. .. Now I have licked blood again and look after Mustangs again. Unfortunately, I find nothing really excessive. Half way usable then it becomes from 38, 39k, whereby also here vehicles have often already snuck a lantern or similar. My general question: Do you have tips how I could optimize my search? Here again a few infos about my search criteria: Convertible, GT, automatic, grey or black, running performance under 20-300, price under or 35k, I know that it would be a good idea for a sportive one, but I have a good idea for a new one.
