Kia Sportage III – Consumer lie

Hello, today I drove the so hotly beloved Sportage 1.7 Diesel (manual gearbox) The seller told me, despite several questions, that the sportage “only” 6-7 L would consume and even though newspapers and forums DAS did not confirm. Nevertheless, I did a test drive with nevertheless not so amazing result. Before I started I drove the tacho and drove exactly 20 km and then from to the gas station and the BC nevertheless not so familiar: result: 10,4 l !!!! I drove AB with max. 120 and in the city anyway not faster than 60… Just find something sad… I confronted the seller with it (Kassenbon). His statement: The engine had to drive first 7000 km and then he would consume about 1 liter less… What a babbeler…. Ne, no.. I like the Kia visually, but a Tiguan is satisfied with 6-6.5 L and weighs as much… (but looks optically shit )
