my wife thought she's be funny and take my car today. She was backing around her car and slid off our driveway into the snowbank. When the car hit, the plastic piece that runs the length of the car (between the wheels) looks like it's pulled away from the car.

I think I see clips in there... could it be that it just snapped the clips? PLEASE PLEASE PLEASE tell me it's just that and that it's inexpensive... PLEASE!

 

I had the same thing happen on my 95 Accord a few years back. The only difference is that the plastic piece actually got pulled back and shattered. I ended up buying a new one for like $20-30 (can't remember exactly), and just snapped on (literally) the new one.

In either case, if you don't have any body damage (scratches, dents, etc), then this will be cheap and easy to repair. I would think Nissan has the same design, and you can just snap the existing one back in (if it's not broken).

Good luck!
