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 wagon 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?

The 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. Moving further on, let's take a closer look at some additional safety-related facts. Both vehicles belong to the small family car segment, which is generally classifying them somewhere in the middle safety-wise, but it doesn't do much to help us decide between the two. On the other hand, taking kerb weight as an important factor into account, the Italian car offers a marginal difference of 6% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that FIAT does have a slight advantage, when all the models are taken into account. These are the official statistics, 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. Independent research findings rank Astra as average reliability-wise, and Stilo is more or less at the same level.That apart, owners of different cars powered by the same engine as these two vehicles rank it on average as 4.4 out of 5.

There's not enough data for me to elaborate on the subject, I'm affraid.

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. Also, you could use the oportunity to find out which car, everything taken into account, would be the perfect choice for you in the eyes of the virtual adviser™, out of 12.000+ vehicles we currently have in our database.
