My ES300 had about 9K miles on it when purchased 11/2003 and now has 40,523 miles and has been the Maytag of cars. In addition to regular scheduled service, the only outlay has been new tires and (battery which was replaced under warranty about a month ago). Lexus sent road-side service with a fresh one and literally 5 minutes later upon arrival it was good to go again. The tires were expensive costing about $900 for Michelins or $1200 for Bridgestone and I highly recommend the latter designed for the car. The Michelins do not handle as well at highway speeds and adversely affected the driving pleasure in my opinion.
The ES300 is stylish and a pleasure to drive with rich wood accents and leather trim. Contrary to many new cars Lexus does a great job padding surfaces for greater comfort. I love the optional moving headlamps, heated seats, rear suncreen and one-touch open/close front power windows and sunroof.
Radio and a/c controls on the steering wheel....a little more insulation for quietness and traditional lighted vanity mirrors vs overhead light on '02 model. Deeper factory-tinted windows (mine were tinted afterward). Deeper cupholders and rear split fold-down seats to trunk would be nice.
