Which small car (i20/Rio/A3)?

Hello, I am looking for a fuel-saving small car (petrol) in the area of Düsseldorf. I drive about 60km of it every day 50% highway, 30% highway and 20% city traffic. My budget is about 13,000€, less is of course better. At Schnickschnack I would be happy about Bluetooth, a cruiser and possibly a navigator, but everything is not absolutely necessary. Originally I thought that I would buy an i10. However, after I had tried both the i10 and the i20 the i10 unfortunately out. At the moment I tend to one of the following cars: i20: http://suche.mobile.de/vehicles/details.html?id=241269675 An almost new car with EC in good time before changing the warranty conditions by Hyundai, so that here still 4.5 years warranty should still be fully valid. Rio: http://suche.mobile.de/vehicles/details.html?id=242618520 Has already half a year and 20,000km on the hump, but is accident-free and should therefore still have 6.5 years warranty. As a runaway: A3: http://2618520 Has already half a year and 20,000km on the hump, but is accident-free and should still have 6.5 years warranty. search.mobile.de/vehicles/details.html?id=242546495 The car is 3 years old and already has 40,000km on the hump. Besides, it is still a bit more expensive and slightly above the targeted budget. How come that the car is so much more expensive? Is the Qaiity better than the others and I have to expect for example less follow-up costs? Is it possible that the more expensive used person compared to the other two? To which of the cars would you advise me and why? Thank you very much!
