1972 Dodge Challenger Rallye

I bought this from the ORIGINAL OWNER of this authentic 1972 Dodge Challenger Rallye with LOW MILEAGE, ORIGINAL PAINT (no rust through), ORIGINAL VINYL TOP, and ORIGINAL INTERIOR (original spare tire has never been out of the trunk). The car is unmolested, in 95% original condition, and has been in storage since 1976 when he got married and started a family. All original documentation (sales brochure, build sheet, original title, key fobs, business card of salesperson, etc.) is available and all serial numbers match. This is one of the most heavily documented cars I have ever seen. I still have the vast majority of original parts that were upgraded in 1974, including the factory wheels, all of which will be sold with the vehicle should the buyer wish to restore to factory grade.

The owner had a custom Rajay Series "E" turbocharger and positraction rear end installed in 1974 by a well known and respected automotive engineer in Akron, OH by the name of Chuck Wright. Chuck was a major player on various engine programs for each of the "Big 3" in years past and operates ProCar Associates in Akron, OH to this day (http://www.procarassociates.com). I spoke with Chuck in 2012 and he vividly remembered the car as a "rocket sled" with drivability even without having seen it in 38 years. Chuck explained to me that back in the day they tested their builds by racing other cars on the street. He said everyone he raced was convinced he had a hemi in it. Chuck reiterated that this is not an ordinary car.

Note: The black color visible in the engine compartment is not rust or grease - it is Ziebart rust proof applied in 1972. I did not detail the engine compartment since it represents the car in its original 1970's condition (vintage coins aren't polished for fear of diminished authenticity).
