Sorry to jump in on this so late in the discussion. I did purchase a 99 rx300 with 113,000 miles on it. It was lexus certified at 35K and had service records since day one. I spent around $2,000 at my local shop to give the car it's 120K mile check up which included everything the dealer would preform and then some. They went through everything in the car from timing belts to tune up to brakes and transmission service. All filters the water pump, tire rotation and alignment was replaced or serviced. The car looks and runs perfect and I do not expect any major problems with it for years to come. In fact the car still smells new. Basic maint OK which since the 120k service has been nill. If you like the vehicle and feel comfortable about taking a chance with it, go for it but try to get the price down a bit. I paid $12,500 for mine a year a go. I upgraded the tail lights and add a spoiler and chrome wheels. It has been one of the nicest cars I ever owned.
