I sold my 69 MACH I about 20 years ago to help pay for school. I sold it to a father and son in West TN and would like to find it to see what they have done with it and maybe see if I can buy it back. The VIN is 9F02R218729, it had a numbers matching 428CJ with auto trans and was all original. Anyone knowing any info about who may own this car now or how I may go about locating it would be appreciated. I know it is a long shot, but I have to try.
