Hey all. I'm considering buying a used supercharger on corral.net. The guy has plenty of positive feedback with big ticket items and I'm going to use my credit card via paypal if I do it, so getting scammed isn't really one of my concerns. What I would like to know is what kind of questions I should be asking to make sure I know what I'm getting and that it's not going to break on me? Any insightful questions I should ask would really help me out. Thanks.
