Don't Bid on that used supercharger that starts out at $700.00 the guy has no feedback because he's a fraud, if you can see there is a subwoofer (supposedly a JL W7) which he was selling under a different user ID and i was winning bidder, i still have not received the woofer or my money back and this was about three months ago. Also a while ago Showdown Motorsports was selling a Supercharger and had the exact same description, "used 6000 miles, missing intake, pulley, bracket". Tell me how can two different people sell a supercharger with same amount of miles and same missing parts, something smells fishy. And this is not the same one Showdown sold because the person who bought from showdown is a user here who i'd rather not disclose. I dont reccommend buying from this ebayer.
