Car A
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.

The Audi TT RS Roadster delivers very quick performance from its 400 hp 2.5L turbo five and secure AWD in a compact two-seater. It’s thrilling and capable for premium road trips, but limited practicality and cargo space keep it from everyday duties.
