Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by diesel engines and utilizing the 4-door sedan body style within the same 'Luxury car' segment, the only major difference here really is their wheel drive configuration (rear for the Mercedes Benz and front in the case of the Rover). The first one has a Mercedes Benz-engineered powertrain under the hood, a 8-cylinder, 32-valves 316hp unit, while the other one gets its power and torque from a 4-cylinder, 16-valves 131hp engine designed by BMW.

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 Mercedes Benz being a slightly better choice apparently. That aside, let's consider some other aspects which affect safety. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, but it doesn't do much to help us decide between the two. Furthermore, if we'd like to consider vehicle mass in this context too, which we definitely should, the German car offers a considerable difference of 19% more metal.

Reliability is not the best thing to consider on the make level, but it is worth mentioning that Rover as a brand displays somewhat better results, when all the models are taken into account. These are the official statistics, while our visitors describe reliability of Mercedes Benz with an average rating of 4.4, and models under the Rover badge with 4.5 out of 5. Independent research findings rank E as average reliability-wise, and 75 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 3.0, while the one under the competitor's bonnet gets 3.9 out of 5.

Mercedes Benz is way more agile, reaching 100km/h in 4.9 seconds less than its competitor. In addition to that it accelerates all the way to 250 kilometers per hour, 57km/h more than the other car. When it comes to fuel economy an obvious choice would be the British car, averaging around 5.8 liters of fuel per 100 kilometers (49 mpg), in combined cycle. That's 60% difference compared to the German car!

Rover 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 beats the other contender by far, making it the best choice without even considering other things. It all continues in the same direction, with Mercedes Benz 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... At the end, as much as I'd like to give you a winner here, it's simply a pure tie if you ask me. Nevertheless, let's not forget that people have different preferences and needs, so what really counts is your personal feel. I'm only here to help.
