I think the price is too high, too. When i substract the discounts for my new ordered Astra K ST with the 1.6 liter machine i payed about 24.000, so the price for your posted car is way too high.
When you search in mobile you have to find the car with same specifications for other prices, right?
I searched a little bit and found offerings for under 20.000 with only 50km, maybe there is not enough equitpment, but i am sure that you find a car with a better price.
