The depreciation of a new car is an inevitable, if painful, fact of life. Some car buyers, however, are likely to feel that pain more acutely than others during the global economic downturn. Take for example the Toyota Aygo driver. According to the UK’s Parker’s Car Price Guide, owners of one of these fuel-sipping minicars would have seen the value of their asset depreciate by just £1,515 (about €1,630, or 18 percent of its new cost) in 2008 -- the lowest cash depreciation on any car, says the guide.
