The Kia K900 is a full-sized luxury car in the truest sense of the word. Size-wise, the Kia K900 matches up well with the Lexus LS, the Mercedes S-Class and the BMW 7-Series. All three models cost far more than the K900. Kia makes the argument that it is simply a matter of badge snobbery. This means some very strong values to be had. Kia buyers can get luxury performance and appointments but for a much lower price.
