I tried taking a test drive of this car. I want to know if noise (whirring) upon acceleration is normal. Also, there was another kind of noise that was accompanying this whirring sound. The 2nd sound was more like the kind of sound you hear when you play race car video games (vroom?).
Any ticking or clicking? Exploding sounds? Seriously, if you have questions about a car you are thinking buying, take it to a trusted third party to be inspected. In my experience Subarus whir and go vroom.
