Ya, I learned the lesson of not getting screwed by car shops. It only took one time. The mechanic also told me he changed the gaskets and I needed a new tranny. It's a done deal with this mechanic, I won't go back to him and I had to bargain him down from 1400 to 950 just to get my car outta there.
Anyway, no roof rack, it's a whine or a hum, no vibrato. Just hum in a high pitch and that's the sound my car makes. Same sound every gear. No sound when coasting or pressing gas with clutch engaged.
