From E-Class to Omega B! Can this work well ?

Tach people, I drive next to my B-Vectra another Mecedes E-Class 200E BJ 1992. The E-Class has been in our possession for 14 years now with 200TKM. Unfortunately we have not taken care of this beautiful car in the last 3 years and now some things have to be renewed or changed. The whole fun costs however 2000 €. I think this is not worth repairing. Now I have thought about putting something on it and me an Omega 2.0 with 136 HP and Automa I don’t know anything about the Omega. But I think I get a big car with good equipment for little money. Only my concern is whether it is reliable. Should I dare? How is the Omega of its driving behaviour? Can you compare it with the E-Class? Greeting PS: If I had only taken care of the E-Class
