I own an '02 Sentra SE-R Spec-v and I have a few problems. Recently I came out to my car and noticed someone had hit it and there is a huge dent in the front bumper, about a foot by a foot. Is that easily fixable or is this going to be a huge cost? Second, there has been a sound coming from my back tires while I'm turning when I first start driving my car that almost sounds like something is rubbing against the tires. I have tried seeing if something is in the way and havent noticed anything. Anyone had any isssues with this?
