156 2.5 V6 /2.0ts

Hi guys. I’m looking for a different car. I was offered an Alfa 156 2.5 from the dealer. He ran about 70tkm and is Bj02. What can you tell me about the car? How is the reliability and how are the current costs? Insurance I already asked and this is OK for me. And how is the difference to 2.0Ts Thank me for your answers. Greetings
