Mercedes-Benz SL63 vs BMW M240I

What's the difference?

An SL sports car has been part of the Mercedes-Benz line-up since the early 1950s, and when I think of this model I see that golden years of Hollywood star (with the great hairstyle) Yul Brynner, in the late 1950s cruising the French Riviera in his 300SL roadster. Or Sophia Loren regularly posing with her 300SL Gullwing coupe around the same time.

Over seven iterations and more than seven decades it has stood for performance, glamour and exclusivity. And after a two-year hiatus the Mercedes-AMG SL63 roadster has made a comeback to the Australian market.

If there ever was a modern BMW that captured the essence of the classic 1602-2002 and pre-Bangle-era 3 Series, it's the 2 Series coupe.

From the lowly 118d diesel to the sublime M2, this model line is the reincarnation of everything that the old 'The Ultimate Driving Machine' company tagline stood for.

Now there's a third-generation 2 Series (if you also count the crisp E82 1 Series of 2007), and right now the M240i is giving off the sort of exciting vibes you might have felt as a teenager looking at a bedroom poster of a 2002ti or 323i.

Does the G42 2 Series deserve to sit alongside such esteemed ancestry? Let's take a deep dive into this most intriguing of BMWs to find out.
