I am a first time owner of a rx300. I love the car but i am suprised at the cost of normal maintenance. The first 1000 miles was free. The next 5000 miles was free. The next 10,000 mile was $104. I am due for a 15,000 mile checkup and they informed me it would be $350.00. I don't know if I should have them due this or just get the oil changed. What do other owners think? rileypackard@hotmail.com
