What alternatives should I consider to a used BMW Z4 sports?
As we mentioned at the start, one of the Z4's closest rivals is the Mercedes SLC. It’s another front-engined, rear-wheel drive, two-seat sports car with a premium badge. It too lacks a sense of driving excitement (that also applies to even the quickest SLC, the SLC 43), and the Z4’s fastest variant, the M40i, has a bit more going for it as a fun sports car.
On the other hand, if you want fun, as well as an extremely polished, precise driving experience, the Porsche 718 Boxster stands tall beside the Z4 and SLC. It’s about as sharp and rewarding as these cars come, although to get a sound like the M40i’s six-cylinder roar you’ll have to pay top dollar and get either the GTS 4.0 or Spyder variant. With their flat-six engines, both cost pretty much double what the M40i tends to go for.
