Why it stands out
The 2021 Mercedes-Benz GLA distinguishes itself in the subcompact SUV market with its modern design and enhanced performance features. This model has undergone a significant redesign, making it more appealing with its SUV-like proportions and improved interior space. The GLA 250 4MATIC is powered by a robust 2.0-litre turbocharged engine, delivering 221 horsepower and a 0-100 km/h time of just 6.7 seconds, which is impressive for its class. The vehicle's all-wheel-drive system is standard in Canada, providing excellent traction and control in various driving conditions.
While the GLA offers a stylish exterior and a comfortable ride, it does face competition from other luxury brands that may provide a more refined interior and additional features at a similar price point. The GLA's infotainment system, the Mercedes-Benz User Experience (MBUX), is user-friendly and includes modern connectivity options, enhancing the overall driving experience. However, some may find the interior materials less premium compared to competitors, which could be a consideration for buyers seeking a more luxurious feel.

It's a decent car, the engine is built more for higher speed vs acceleration.
