Nice LL, here in the Washington,D.C. area we have Schwinn Stingray Choppers the 20-inch not the XL models, that are easily purchased for the price you paid for your's. Congrats, and FYI these bikes were sold thru Walmart & Toy's-R-Us stores with prices starting at around $149.00
The Spoilers, XL Stingray, and Special Edition's " Squadron Model ", and the " Spider Model ", and the Stingray Chopper Electric model ", and the Stingray 3-speeds Models ", were mostly sold thru Schwinn licensed dealers or authorized Local Bicycle Shops.
