Although silver is one of the best choices for a sunny country, I wouldn't choose that color for the simple reason that I got sick of it! I see so many cars in silver nowadays, even our family car is silver! Purchasing a car in silver is a trend that started more than 5 years ago and it seems that it's going to stop because of white.Anyway, I would take the S5 in black.Yes, I know I live in a hot country and black is the worst choice but still, nothings cooler than a black S5!
