Q What is the difference between a used BMW Z4 M Sport and M40i?

Every used Z4 M Sport comes well-equipped as standard, with the electric folding roof, BMW Live Cockpit Professional, 18-inch alloys and leather seats across the range. The M40i builds significantly on this, adding M adaptive suspension, M Sport brakes with blue callipers, electric memory seats, and heated seats and steering wheel as standard alongside its more powerful six-cylinder engine. For the most driver-focused, most thoroughly specified used BMW Z4 for sale, the M40i is the one to go for.
