BMW 125i vs BMW 220i

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.

If one is good, two must be better, right? Or twice as good. The question is whether that simple equation adds up for BMW's upgraded 1 and 2 Series siblings – the former, a range of five-door hatches, the latter, a line-up of cabriolets and coupes, with a major addition in the shape of the full-house, performance-focused M2.

Prices are up, and changes are mostly under the skin, so you're not getting  big visual bang for your extra bucks. But the new and improved 2 has plenty to offer when it comes to added spec and tech.
