Calibra 2.0 85KW consumption and so on……

Hello, actually come from the Corsa area. But have a few questions to you Calibra riders especially to those who drive a 2.0 with 85KW! Because for an apple and an egg would get a Calibra with 2.0 liters machine. The car has automatic and is BJ. 1994 and has 174 Tkm on the clock. Climate us also has further extras. Now however to the questions: What consumes the car so in the city??? What should one pay special attention to (rust etc….) How long does the M otor on average (with normal care)??? Thank you the-always-laughs
