BMW 125i vs Mercedes-Benz GLS-Class

What's the difference?

If you think it’s a Mercedes-Benz A-Class you want or maybe an Audi A3 Sportback or even a Volkswagen Golf, then stop and read this first before making a purchase.

The BMW 1 Series alternative isn’t just another prestige little car, because there are some fundamental differences between this 1 and those others, and they could cause you to totally rethink your decision.

If you’re already keen on getting a 1 Series then you need to read this, too, not only to help you find the right one, but also to alert you to what might be a couple of uncomfortable truths.

The ‘Upper Large SUV over $120K’ segment of the Aussie new-car market is what you might call the top end of town, not only in terms of the extravagant models available but also their purchase prices, which stretch well into six figures and require monthly lease payments that rival home mortgages.

It’s where you’ll find some of the most prestigious marques in the automotive world including Rolls-Royce, Aston Martin, Bentley, Ferrari, Lamborghini, Range Rover, Lexus and BMW. And, of course, Mercedes-Benz with its big GLS which represents the flagship of the German manufacturer’s SUV fleet.

It was given a refresh in 2023 with cosmetic and multimedia upgrades along with powertrain enhancements, but there have only been minor changes since then. We were recently entrusted with the keys to the latest GLS to see if the ‘S-Class of SUVs’ leaves any room for improvement.
