Support for offers and where/how to buy the best

Hello dear Seat fans, I plan to purchase the Seat Leon with the style equipment. This is in the list for 21,240€. The windows should still be tinted. Return sensors, Navi, multi steering wheel + media center. At the “dealer of my trust” I received an offer for 19,400€ plus overpass, KSB contribution and registration, makes 21,194€. A buddy says that this is not really a lot of discount for a new car purchase. Now I am unsure?! And has someone ever a car running on the Internet? They are significantly cheaper but I’m not sure… help! LG Monique
