I bought my '72 Challenger Rallye back in Nov. 2003. It's mostly original. I'm the 3rd owner.
The 2nd owner bought it back in 2001 from the original owner and just let it sit around in a barn in New Hampshire because he spent most of his time racing Mustangs. He originally wanted a Cuda but this Challenger was too good to pass up. (He got it for $3,000)
I met the original owner when I picked up the car. I drove it by on the trailer to let him see it again as he was sorta close by in New Hampshire. He bought the car 8/31/1971 from MacKensie Motors in Mancester, NH, 4 days after getting out of the Army. It went through the typical phase in the 70's of big tires, Cragar S/Ss, and air shocks. He really loved this car but sold it in 2001 as he thought he "blew the engine". Turns out the neck for the radiator fell off so I soldered it back on and it hasn't been a problem since. He made me promise him if I ever sold the car to call him first as he still loves this car.
The original owner took real good care of this car. He even kept some of the original paperwork, ie the hand written and typed invoices from the dealer when he bought the car, owner's manual, certificate of title, etc... The engines never been apart, numbers matching 340ci with a 727 and Slap Stick. Doesn't blow any smoke. Still in the original color, code TB3, Super Blue, but painted a couple times. All the sheet metal is still original. The original steel 14x5 wheels and hubcaps are in the garage. I found 1.5 build sheets but the mice got to them before I did. The car presently has brushed steel 14x6 Magnum 500s but will upgade to Keystone Klassics with 275/60s in back.
