Something everyone should know about lexus , we also work on them and every once and a while I get stuck with one . It is unreal how much the parts are for these cars , actually higher than Mercedes dealer list . Some things you can get from aftermarket some you have no choice but toyota. Dont expect the prices for repair on your lexus to be lower than your Mercedes. I have alot of customers going back to Mercedes due to this. This is not to make you feel down about your new car ,just be prepared. Dont let the timing belt go too long ,and make sure to change the oil every 3k miles or you will have problems.
