My friend has a red s13 for sale with the cleanest underbody I have ever seen on a 240… literally no rust anywhere underneath. I chilled with him just before school started (last wed for him) and I saw the car on the hoist myself.

Best bet is to call him. He’s been trying to sell this for a while now. Looking to get back into the rotary scene. I hope everything goes well.
