FLEET NewsNet looks at how new cars taken on to a typical fleet might perform over the next three years/60,000 miles. Using data from used car expert CAP Motor Research, we benchmark two cars against each other to see how they perform over the traditional fleet cycle. This week’s contenders are German prestige diesel rivals which vie for position in the company chairman’s parking space – the Mercedes-Benz S-class and the Audi A8 quattro.
