Comparison Review

Comfort
Due to its greater rear head- and legroom, backseat passengers will be able to stretch out a lot more in the Kia K4 than the Mercedes-Benz C-Class. As far as headroom and legroom go, there's not much difference between the Kia K4 and the Mercedes-Benz C-Class in the front seats.

Convenience
With the Mercedes-Benz C-Class you will definitely be making less frequent stops at the gas station than with the Kia K4, due to its tank size and fuel economy.

Cost
There are a lot of factors to consider when calculating the overall cost of a vehicle. The main consideration is Manufacturer's Suggested Retail Price (MSRP). Based on MSRP, the Kia K4 is clearly a better financial choice over the Mercedes-Benz C-Class.

Dimensions
Since the Kia K4 is much slimmer than the Mercedes-Benz C-Class, it'll be much easier to find a wide enough space in a crowded parking lot. When looking at overall length, the Kia K4 takes up about the same amount of space in your garage as the Mercedes-Benz C-Class.

Handling
The Kia K4 has a smaller turning radius than the Mercedes-Benz C-Class, allowing you to more easily maneuver in and out of tight spots.

Performance
When it comes to horsepower, the Kia K4 is significantly less powerful than the Mercedes-Benz C-Class. The good news is that, reportedly, cars with lower horsepower engines often have lower insurance premiums.

Powertrain
The Kia K4 has much less torque than the Mercedes-Benz C-Class, which generally means that it won't feel as fast or powerful.

Utility
In terms of seating you'll be able to fit the same number of people in both the Kia K4 and the Mercedes-Benz C-Class.
