This 1964.5 Mustang was produced July 17th of 1964. It was a Dearborn produced car that was sold new into California where it has spent its entire life. Though the serial number decodes as a 1965, these early cars are referred to as 1964 1/2′s by enthusiasts as they have many differences from the later 1965 models. July 31st is considered the end of production for cars that can be designated as 64 1/2′s so this car was near the end of that run (which started in March of 1964). Most differences are very subtle, while others are more obvious such as a generator instead of an alternator.
The Wimbledon White paint was a popular choice and the original finish on this car does present well in the photos outside of some surface rust in spots. Again a note to sellers, do not photograph your car under a tree on a sunny day!
The engine is the 170 CID six-cylinder unit which was only avaialble on the ’64 1/2 cars. Later cars had the 200 CID six banger. The red valve cover and air cleaner are correct for a ’64 1/2 Mustang with the 170 CID engine.
The interior looks to be in great shape, consistent with the 66,000 miles on the odometer. The car is available here on eBay in Davis, California with an opening bid of $7,200.
