Bought my 2003 RX300 SE Navigator in January with 53000mls on the clock from a Lexus Main Dealer, paid £10,400, inclusive of Service, RAC Cover and one years full Lexus Guarantee. The car is amazing, really comfortable and a pleasure to drive, money well spent. On mixed driving I get about 26 m.p.g and 32 m.p.g. on Motorways.
