6. Audi S5 (3.0)

Original price: £41,975 (R537 280) - Price after three years and 57 936km: £23,350 (R298 880)

Another range-topper, demonstrating that it is often the cars at the top end of the line-up which hold on to their value the most.

The S5’s styling may be understated compared to M BMW’s and AMG Mercedes but make no mistake, this is a pacey, yet practical, drop-top.
