Buying decision Middle class limousine

Hello I would like to buy a car in the next time. It should be a limousine, should cost a maximum of 20 -25k and the equipment should contain at least leather, climate and Navi. No older than BJ 2008 and a maximum of 35000 km on the speedometer, also at least 150 hp and an automatic transmission. And it should have all-wheel drive. After a long search of the car market are now still 4 cars in my closer selection: Audi A4: But with the equipment at the price I get almost n Opel Insignia: Would be my last choice for the price but from the point of view. Suzuki Kizashi: I like optically pretty good and comes with very good equipment is to have as a new car in my budget. VW Jetta the new one: I like optically very good but will easily exceed my budget with the equipment. Now I would like to know what you generally think of the four cars? Which would you recommend?
