2023 BMW 3 Series Summary

Back in the day, the 3 Series sedan was often the entry to the brand for first time BMW owners, and for good reason. They offered practical interior space without compromising on engine performance.

And they simply looked good, no boring nanny design elements. Then the 1 Series came along and price points bumped up, so how does the ‘entry’ BMW 320i M Sport live up to its long-standing reputation?

With an updated dashboard that brings the interior and tech up to market and a sharper exterior design, it more than holds its own at the table of luxury sedans, despite hard competition from the likes of the Audi A4, Mercedes-Benz C200 and Jaguar XE.

However, if the Merc is a placid and well-behaved mare… the BMW is the barely-broken-in bronco and it takes a certain kind of ‘rider’ to enjoy what the 320i has to offer.

I’ve been discovering just that this week with my family of three. What did we find out? Read below!

2025 Smart 3 Summary

Smart is back.

Not with the classic ForTwo two-seater city car, oddball four-seater ForFour hatch or dinky Roadster targa top. Those were yesterday’s cars.

Today, Smart – as a 50/50 joint-venture between Germany’s Mercedes-Benz (the brand’s originator) and China’s Geely – is all about SUVs. Electric SUVs.

The boxy #1 (pronounced “hashtag-one”) is a small SUV and the sleeker #3 is the coupe-esque performance crossover version. Both are made in China and use Geely technologies.

We take a long, hard look at the range-topping #3 Brabus, the speediest, sexiest and exxiest of the lot. Let’s go.
