I have a 99 RX300 with 45k miles. No problems, except 02 sensor blowing on me, which was replaced under factory-OEM warranty. Just to be safe, I bought for $1800 a 1sourceautowarranty diamond plan, which will take care of me thru 100k miles/5 yrs. Just to be safe. I can't imagine having problems, but would recommend it. If you can afford this car, you can afford to pay a little for peace of mind insurance against costly repairs -- not because it's a bad car, but because parts/labour cost so much.
