Here is a 65 K code Koupe listed on Ebay by seller "matt1964mustang" with a starting bid of $3,900.00:
1965 mustang coupe rare K Code 289 Hipo four speed. The car is rusty! It has a title, original door tag. The car is a factory 289 hipo car K code Wimbledon White with bright red interior. The car was not a factory GT car. This car is not for the average builder. It will require extensive metal replacement. I do have a 6 cyl body that the some of the factory parts could be used on this car. Structure mainly. This is your chance to own a part of mustang history. Unfortunately the drive train is not with this car but is obtainable with cash and looking. I have found drive trains for three of these cars myself. Swap meets are your friends for HIPO cars! Thank you for looking. The luck winner must put down a 1000 deposit with in 48 hours and contact me with arrangements to pay the remainder.
Thank you, Matt
