Buy Giulietta – yes or no

Hello, question to the Guilietta owners. I carry the idea of giving away my current car in the medium term and replacing it for something more modern, fuel-saving. Choose from: Hyundai I30 (new model) Kia Ceed (new model) Alfa Guilietta I need a diesel, also at the risk the diesel will soon be more expensive. As long as there are no durable engines (fuel) that can keep up with the diesel power and fuel consumption, comes a petrol I need a little comfort and technical games. New car or day registration… depending on the offer. 5 doors must be. Costs at the moment: tax 355 € , insurance 628 € including all-inclusive per year, consumption about 5.9 – 6.3 liters on 100 km, inspection costs about 250 – 400 € depending on which. I already had an Alfa, that was a 147th horny car, horny road situation, but lots of quirks and in addition came the well-known tooth belt crack. My question now, one says the Alfa What is it really like? Is the Guilietta recommended? Are there any vulnerabilities? Which? What costs need to be planned? (tax, insurance 85%, consumption) I ask for information. Thank you very much.
