Well, these are two pretty similar cars we have here! It's only details that could potentially make the difference. Considering they both belong to the large family car segment and utilize the same 5-door wagon body style and the front wheel drive system, it all comes up to the specific diesel engine choice they offer. The first one has a Isuzu-engineered powertrain under the hood, a 6-cylinder, 24-valves 177hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 125hp engine designed by Opel.

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 SAAB being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the large family car segment, which is generally a good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, when it comes to weight, a factor that most people underestimate, the German car offers a marginal difference of 4% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that both brands display similar results in faults and breakdowns, when all the models are taken into account. That's the official data, while our visitors describe reliability of Opel, as well as SAAB, with the same average rating of 4.2 out of 5. Independent research findings rank Vectra as average reliability-wise, and 9-3 is more or less at the same level.Above it all, drivers of cars with the same engine as the German car rank it on average as 4.8, while the one under the competitor's bonnet gets 3.9 out of 5.

Opel is undoubtly more agile, reaching 100km/h in 1.7 seconds less than its competitor. In addition to that it accelerates all the way to 222 kilometers per hour, 22km/h more than the other car. When it comes to fuel economy the winner has to be the Swedish car, averaging around 5.7 liters of fuel per 100 kilometers (50 mpg), in combined cycle. We can't ignore that 28% difference compared to the German car.

Opel 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 Swedish car offers slightly better overall protection and takes the lead. From there things take a different direction, with Opel outracing its opponent in any situation possible, making it better choice for boy racers. It does come at a cost though, and that's the fuel consumption... It's really tough to make a final decision here, but if I'd need to, I'd say SAAB. Anyway, that's the most objective conclusion I could've came up with and it's based solely on the information found on this website. Aspects such as design, practicality, brand value and driving experience are there for you to measure them out.
