Thanks for the replies guys.
Well yeah, I know what you mean. The rear towers are clean from what I could see.
And I saw the 12,000$ in reciepts, it was a FAT stack. All from the same two places. But you have to look at this as it could go both ways. That much in receipts means one of two things...Got to take it for a drive and the KA is definitely sounding rough. But thats no problem as it is going to be a SR swapped car. The rust is pretty darn bad, and it's making me either want to a) lowball him because its really not worth what hes asking right now b) buy a shell from the states and swap all these parts onto it. Maybe I'm getting to far ahead of myself. I kinda would just like to buy a car thats rust free off the bat and ready to swap but if this could save me some money/be worth my while I may go ahead with it. Considering the rust...I don't think its worth it.
Here are some more pics. The rust is indeed real bad. Share some opinions, thoughts, and even suggestions. He HAS to sell this by sunday this weekend, so I might get this for bottom dollar and take it for parts/sell parts.
