Bad rust under floor pan?

I just got this pic (and more) of a vert I'm interested in. Is it just some kind of underbody cover that rusted through or is it something more important? Should I stay away from the car?

Thanks!
Lou

That IS the floor pan. Stay away. Far away. Unless you like to do resto work!

I don't know what the underbody of an f-body looks like. Does it have just one layer the seats are mounted to? Wouldnt' that be kinda "ungood"?
I thought I saw some frame above the rusted metal, is that the actual frame that holds the seats? Is it just some sheet metal cover that rusted through on the bottom of the body?
Once again, I have no idea what the body looks like so please explain it to me like to a 4y/o.

that is not that bad, anyone here from canada. this is normal, mine was a hell of alot worse then that. It looks ugly, but this will definatly affect the price your going to pay, and give you something to do!. I would shave off 10 percent of the asking price on this one for ever spot like that or at least have the seller adjust the price appropriately, however, i don't mind re-working stuff like this, so it is only my opinion

what you are seeing is a whole through the floor, the frame work you are seeing is the frame for the seat. the floor in an f-body is an our skin only with the inner frames for mounting the seats, and since they are unibody, the body is also the frame. The hole you are looking at is definatly repairable, take a look at some of my threads. It looks alot more scary than it is!. let us know if you buy, we can help you get it all together, easily and cheaply if necessary!

This car has allegedly been in Florida all its life, mostly driven on the highway between two cities. How would that happen in Florida? Is ocean water on the beach strong enough to cause this?
So I see the F-body does have a floor frame coverd on the bottom and top. That's good. So that could be just damaged/eaten sheet metal on the bottom. I hope.
Actually, the owner claims he got some rain water in the vert and that's why the floor is rusted. And that could mean that the car was possibly not exposed to salt.
I'm having another fellow member (thanks Al!) go look at it this week. I won't fly over there until I know the condition of the whole car.
So if this thing is repairable, I am still interested in the vert.

BTW: it's a black '89 IROC with black leather seats and interior. The only things that need attention is the floor, the gauges (tach & speedo don't work) and the top (new needed). 110K miles. 305 TPI, freshly rebuilt from scratch. 5sp. New tires.
What's this baby worth, in y'all's opinion?

Sorry for the long post, it's just a hard decision to make.

Hey, I'm Canadian too... I guess I'm just kinda lucky with my cars... my first car (88 Firebird) was a BC car and it never saw salt, so it was completely solid... my 89 GTA, the floor pans barely even have any surface rust of them! The floors only have a small hole where they meet the rockers... I guess I'm just lucky, cause the previous owner of my GTA did winter drive it a few years (thats crazy!)

But hey, I guess someone with a welder, some skill, and some patients can fix stuff like that!

Just run away as fast as you can. If that is a Florida car he must have drove in salt water. If you buy that car, be like the Fintstones and use your feet.

i would check the engine comparment for rust, check how flimsy the front fenders are where the plastic clips on, pull the trunk carpet, check the rear quarters REALLY well and pull the carpet in tha passenger compartment. pull the carpet to show him why you want alot of money off the price. show him quotes of how much a floor pan costs.
that is if you still want the car

i think in the end it will come down to how much you want that specific car, and if you are willing to make the required repairs, however, i would work the price regardless

I don't know how much work you are willing to do or how much you are willing to pay, but remember there are a lot of Camaro's out there. If you are looking to get something just to drive, forget it- your butt will be on the pavement if that is not fixed. Though it is a nice looking car-

Thanks for all the comments, guys.
I ended up turning it down. The car looks alright on the outside but as Al found out today, it has a lot of problems and would require great amount of work. I did not want a project car. I'm looking for something with a bug or two but not a "fleabag".
I'll keep looking, although it is hard to find the right car to satisfy all my demands.

Stay away from that car! If you look at the rear trailing arms, they are most likely rusted really bad too right where they connect to the floor pan...I lost my car due to this! It ripped them completely from the floor pan and dropped the rear end!
