my car has been putted into using for two years and 4 months since l bought it in May 2010. It has driven nearly 50000kilometers. There is a common saying in china,“two years a camp”. It is usually used for describing people. But l think that it also describe my car’s condition perfectly. In the beginning two years, l just do some routine maintenance regarding maintenance guide. But now l must pay for a series of maintenance with time passing. L make a list about car’s maintenance, the item includes as below: changing tires、maintaining surface bearing、replacing battery、exchanging bumper、changing brake oil、replacing transmission oil、changing sparking plug。If l do the forementioned items in 4s center, it almost costs 8 thousands RMB. When l see this number, l am almost crazy. It is necessary to do the upper items. If l don’t doing the items, my car will face some safe risks. L can’t imagine the result. But it is lucky that l find a garage which can ask for 4 thousand RMB for resolving it.
