Buying advice Suzuki Swift Sport (new or presenter)

Hello together, I have to get a Swift sport before me. Currently, however, it is before the question demonstration car or day registration. The demonstrator has about 4000 down and was used for test drives and as a car rental. Since it is a sporty car I guess that has not taken place much with. Price negotiating the car house does not want to big. 20000 smooth. Incl. winter tires on aluminium and summer on original aluminium. And incl. 2 years warranty extension. He stood on the Wi nterreifen at the moment there for 19500. I then said if they give me the summer tyres with original aluminiums. She then meant that the winter tyres with aluminiums would cost about 900 and they would then leave it to me for 20 smooth. The advantage would be that the AH is not far away. So for future services etc quickly reachable. About 50KM far away there is an AH that offers some Swift sport with daily registrations. They would have only the original rims and tires with them. But for 19800. n I better advise, if I get some extra winter tires but drive in for it myself and know what happens with it from the beginning or how do you see it? Colorwise I can’t decide so much between blue (premier) and red (day registration). Just wanted to hear your opinions.
