Greg - Your Car Angel shares why the Lexus ES 300, ES 330 and the ES 350 are the best used Luxury cars to buy. High quality parts, high quality Japanese manufacturing make this the most reliable sedan you can buy. Put those together with highway miles and you get a car with very high miles. 596,000 miles is ultra high mileage. All the older 2002-2006 ES cars were built in Japan. The American and German manufacturers could not match the quality of the Lexus product.
