I have a 1997 es300. The car drives smoothly but the engine sounds differently than it used it. It makes a loud buzzing sound which gets lounder as the car accelerates. Anyone here experience anything like it or know what the problem may be? Thanks.

What is the best Lexus Service Center in New Jersey? I am planning to get my scheduled maintenance in the central New Jersey area. Does anyone have any recommendations or warnings about the service centers there? Thanks.
