Many like to run in the GRAY area and represent the car as numbers matching when decades ago that would have meant that the car was correct and original as the car was built and sold as. Today people know darn well that their car didn't come with (BORN WITH) drivetrains or sheetmetal etc but constantly represent them as so. I would guess that less than 5% fall into that category,look at all the requests for engines, transmissions, third members and most of the car. No big deal really, sellers need to be a little more forthcoming that these pieces have been replaced and they are not born with, that cuts to the chase of unscrupulous sellers selling something that is different then what some are hoping to purchase. There are just a few on here that can decipher every little nuance of these cars, that's why we hire them for an honest description and evaluation before we start peeling off some BENJAMINS.
