There is this guy selling a Cobra on EBAY and it's selling for $3,000. 

Cobra Engine Powered Ford Mustang LX with R1 racing seats and Sparco fourpoint seat belts. The stock engine was replaced with a Cobra engine for greater performance and easy burnouts and faster ecceleration also the transmision is changed and CONVERTED TO MANUAL TRANSMISION and stock air intake is replaced with an aftermarket cold air intake,for better grip the tires was replaced with performance ZE502  Falcon Ziex tires.

Needs to sell fast due to a bad habit of speed!!!! - too many traffic violations. LOL
