Got pics? Foxes are kind of worth anything now. If you find the right buyer, and your car is nice/rare enough, you can pretty much name your price.

I don't think he is talking about selling it, haha. Your #5 cylinder values are a little low yes, but not low enough that it's going to be a problem. Your lowest one was 118psi, and that is only 12 under your other norms of 130.
