Weaknesses of Calibrase

Hello together, since I will soon be 18 I need of course a fancy vehicle, and since already from a young age on the Calibra it should become also one. I am only unschließig, because I have heard from many Opel drivers that the dinger are totally vulnerable as also the Vectras from this time, i.e. steering gears etc. I have to drive 35000 km per year, because of my training, therefore it should be a reliable car, where as much as possible nothing comes up . I’m ready to invest the 500€. Please tell me honestly which weaknesses of Calibra. Thanks for the honesty and help guys MFG Fabian
