Two significantly similar cars, no doubt about that. Still, each one has something different to offer. Having both cars powered by petrol engines and utilizing the 5-door wagon 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 4-cylinder, 16-valves 163hp unit, while the other one gets its power and torque from a 6-cylinder, 24-valves 150hp engine designed by Rover.

Both vehicles got tested by European New Car Assessment Programme (Euro NCAP), with the same number of safety stars gained in the process. Still, apart from the official crash test results there are other things we need to be aware of. Both vehicles belong to the luxury car segment, which is generally a very good thing safety-wise, still it doesn't help us solve our dilemma, does it? Furthermore, taking kerb weight as an important factor into account, the German car offers a marginal difference of 7% more metal.

Manufacturers have been building their reliability reputation for decades now and, generally speaking, it appears that Rover as a brand displays somewhat better results, all the models observed together. 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. Some independent research have also placed E as average reliability-wise, and 75 is more or less at the same level.That apart, owners of different cars powered by the same engine as the German car rank it on average as 5.0 out of 5, exactly the same as the other one.

Rover is a bit more agile, reaching 100km/h in 0.1 seconds less than its competitor. Still, it lacks the power to win the top speed competition, topping at 203 kilometers per hour, 9km/h less than the other car. When it comes to fuel economy the winner has to be the British car, averaging around 8 liters of fuel per 100 kilometers (35 mpg), in combined cycle. We can't ignore that 16% 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 offers slightly better overall protection and takes the lead. From there things take a different direction, with Rover offering somewhat better performance, just enough to call it quicker. To make things even better, it consumps less fuel! All together, there's not much more to say, in this case I wouldn't even consider anything but Rover. 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.
