Cruze – recommended?

Hello, my daughter plays with the idea that she might be able to separate herself from her Astra J with a 100 hp engine in the foreseeable future due to unreliable hum and roaring noise. Visually and from the processing she likes the Cruze with an angle rather well, even price-wise you can’t complain (model-dependent and discount). Now some questions: should you stay at 1.6 or rather prefer the 1.8 – engine? Are the Opel engines? Is the rust protection comparable with the local car? Gib t it is susceptible parts and the engines are stable? How is the technical material quality and above all the reliability? Well, a little bit a lot at once, but it would be nice if some would report their experiences. The sellers in the car dealership are dealing with nothing at all, not at all practical. I would like to thank you in advance. Greeting Jüppken
