Purchase advice Leon ST FR 1,8 DSG Full demonstration car

Good morning Together, for a few weeks I am here silent reader. I am about to hand in my A4 and get a Leon. I have now received an offer from my dealer on site and would like to know briefly, is the offer appropriate? It is about a Leon ST FR 1.8er DSG with (almost) all equipment (roof sky is not black and without Kessy but otherwise everything should be there) as a demonstration car with currently almost 4500km on the clock, EZ 11/2017. e 28500€ as a financing price. After a night’s thinking time I tried to push the price still (would like to make a balloon financing over 48 months incl. warranty extension and maintenance plus), but almost no chance. I still managed to go down 4€ in the rate and get on the winter tires 150€ discount (If I don’t find now so bulging, more is supposedly not possible) – At mobile.de however, even some new cars are offered to the course… Is the P rice ok? Supposedly there are other interested parties and I have only a few days left for the decision. Greetings and many thanks already
