Car A

Mazda MX-5 Miata

A two-seater focused on value and pace, the Mazda MX-5 Miata pairs 6.5 s 0–100 km/h performance with 7.6 combined consumption. Strong reliability (85) and a 4-star safety rating help it work day to day if you can live with a 130 L trunk.

Car B

Mercedes-Benz SL 550

A two-seat V8 performance car with 4.6 s 0–100 km/h and a useful 300 L trunk, it suits spirited drives and weekend road trips. Limited seating and 10.1 L/100 km fuel use reduce its appeal as an everyday hauler.
