You'll be surprised how much people are will to pay for an original Stingray. The 5-speed stick shift Krate models are almost double of the listing the OP posted. Even the 2004-05 Stingrays command inflated prices.
Buy a
Schwinn El Dorado if you want a Stingray looking bike..and it only costs about $150 shipped.
The style is still popular with the low rider crowd and no name knockoffs are being sold that look pretty good. They carry many of the parts, so you build one yourself. Overall quality is unknown, so you take your chances,
