So like it says, my undercarriage got smashed in. i noticed it when i was cleaning my car and noticed the floorboard was popped up. At first i thought something was under the floormat, but i wasnt that lucky. Its popped up probably at least an inch. I dont know what happened. I let my sister borrow my car not too long ago. I suspect she hit something and didnt tell me. I'd like to think i would remember hitting something that would leave this kind of dent. Here are some pics. (note: Pics are kinda big. didnt have time to shrink them down.)

This is on the passenger side of the car.

This is on the drivers side of the car. It looks like it might be dented but not nearly as bad.

Kind of hard to see, but i think you might able to see the floorboard popped up.

Ok so first things first. What the he** could she have hit that would cause that kind of dent? My god. Ok, so now what do i do to fix it? Just pull up the carpet and hit it with a hammer? If it hadnt noticebly pushed the floorboard up, i wouldnt bother with it. But its definetly noticeable. Any advice you guys could give would be great. Would i be better off taking it to a body shop? If theyre just gonna bang it out with a hammer, i'll do it myself. Thanks alot guys.

Hmm...looks like you tried to jack up the car on that 'beam'

I have the exact damage on my car. I jacked it up (back when I was a newbie) using those 'beams' and caved in the floorpan.

I've yet to repair the damage, but I plan on taking the carpet up and straightening it out w/a mallet. It shouldn't come out too bad; as you said, it's difficult to see it.

Yup, BFH......

Is that a repost? Or does more than one poster have imaginary sisters??!

It's a repost...I've been away for a while and replied to this one; it was the first one on my way to page 1 from page 48.
