last night was pretty dark and i was talking on the phone didnt see there was a median separate the right left lane ,i just ran over it to the wrong way with my nismo and had to back up my car . so i scratch it twice ..........lucky thing is the bumper is fine ,no much damage ,but the exhaust sounds weird not as clearly as before and the clutch pedal not as hard as before too ,feel nothing when i step on it ,but it still works fine, if i take it to the dealership ask them to replace the whole exhaust and clutch pedal will they do that for free ?? if there is more problem found under the car will they fix it all for free or i have to be fully responsible for that !!! someone please tell me what to do ,,because i cant not speak english very well !! thanks guys !!!!!
