I am looking at a 2007 250 with a 6spd. Everything seemed fine and during the last test drive I noticed a noise coming from the Transmission. When I press the clutch it makes a whirring noise, when I let it out the noise goes away. I was told it was the throw out bearing and that it needs to be replaced. So I call Lexus and they tell me 1300 for a clutch replacement and another 1300 for the fly wheel. I havent bought the car yet and the dealer wants 19k for it. It has 54k on the odometer. Should I buy it and replace the clutch ONLY or could there be flywheel damage as well? Or just say screw it and get the exact same car with an automatic for 500 dollars more? What do you all think? Either way I am getting an IS, my and I absolutely love it.
