Newbie rust question Options

[zprovo]

Hello!

I am new to the world of 914s. I was looking at a car on sunday that had good longs, the hellhole looked good, floors looked good (the interior is pulled out). All the exterior sheetmetal is nice and straight. Then I popped the hood to the "frunk". There was a big hole in what I would call the passenger side firewall...what is this called in a mid engine car?

Picture for reference below


I think this is the area where the windshield washer bottle would usually reside. There are a few smaller holes under where the gas tank should be and the pedal box is pretty rusty. Apparently mice had taken up residence, chewed up the wiring and created a bunch of rust while relieving themselves.

How scared should I be of this car? It's been sitting for 31 years, I can handle the myriad of mechanical and electrical issues this car will have, but I will probably need to sub out the rust work.

Thanks in advance for any thoughts.




I don't know why I can't get this to load with the correct orientation... that is the hood spring on the lower left for reference and passenger door beyond.
