Virtual Adviser's™ opinion
Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Not only that they both belong to the small family car segment and utilize the same 5-door hatchback body style, they are even powered by the same FIAT-developed diesel engine! There is not much there to point us towards one vehicle or the other. Or is it?
SafetyThe first thing to look into here would be the results from European New Car Assessment Programme (Euro NCAP) tests performed on the two cars. Good thing is that both vehicles got tested, with the Opel being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but that fact doesn't break the tie between the two cars. On the other hand, taking kerb weight as an important factor into account, the Italian car offers a marginal difference of 1% more metal.
ReliabilityReliability is not the best thing to consider on the make level, but it is worth mentioning that FIAT does have a slight advantage, at least on all of the models level. That's the official data, while our visitors describe reliability of Opel with an average rating of 4.2, and models under the FIAT badge with 4.3 out of 5. Some independent research have also placed Astra as average reliability-wise, and Stilo is more or less at the same level.We should definitely mention that owners of cars with the same powertrain as these two vehicles rank it on average as 4.5 out of 5.
Performance & Fuel economyThere's not enough data for me to elaborate on the subject, I'm affraid.
Verdict
FIAT appears just a bit more reliable, although the difference is truly marginal. The most important thing when deciding between any two vehicles should always be safety, both passive and active. In my opinion, everything taken into account, the German car offers slightly better overall protection and takes the lead. When it comes to performance, both vehicles provide similar experience, so I wouldn't point any of them out. Fuel consumption is more or less the same. It's really tough to make a final decision here, but if I'd need to, I'd say Opel. In any case that's my personal view, built upon all the data available to me. What should decide here though is the way you feel about the two vehicles, and I hope you'll find my guidelines useful in the process. In case you have two minutes to spare I invite you to define your needs, desires and budget and see which car would be chosen by the virtual adviser™, among thousands of similar, yet so different vehicles.
