We bought this car used in March of 2008 (Certified though), and we have had absolutely no mechanical problems with it (minus one tire that had an improper seal, easily fixed)! One of the best cars we've owned! We used to be a Honda/Volvo family, but my husband acquired my stepmother's 2002 RX300 in 2005, and since then, we have fallen in love with the brand. A reliable, QUIET car! Only improvement would be better mileage around town, we're getting about 17.5, which is still good for a V6! Kudos, Lexus!
