Buy KIA Ceed Ex- Car Rental?

Hello, a used Ceed (first registration 01/19, 20,000km, 136hp, switch) has been in a car dealership nearby since yesterday, which is actually perfect. A test drive went smoothly. No defects. TÜV/ AU and the first inspection (so far no one has been done) would be made. Discount to the new car ~45%. Unfortunately, this is a rental car that ran at a large chain, probably at an airport. Warranty is still available for a few years. e not off. So a new clutch would not be included e.g.. Would you buy such a vehicle? Pfleglich will certainly not be dealt with with the vehicles. Besides, the clutch and the engine will certainly not be spared (cold full gas drives, switching errors & co.) I am looking forward to your opinions.
