So....What is YOUR opinion on VIN swaps ?

Saw someone get taken for $20k on a supposed '71 Cuda like this.

They brought the car to me after the sale for appraisal and verification. Nose said '71. VIN tag said '70 Barracuda with a 318. Core support had a totally different sequential number and the data plate and broadcast sheet was missing.

Another was a guy who had a supposed real '68 Charger R/T. The numbers on the data plate showed a real R/T, the VIN showed a '69 318 car, and the numbers on the core support and drip rail didn't match either the VIN tag of the data plate. Broadcast sheet was from another car to boot. Guy wound up taking a close $40K hit in the final sale. He found a buyer who just wanted a nice (really nice) '68 Charger with a 440 and could care less about the numbers, but when he thought it was an original R/T car he was advertising it for $50k. Sold it for $10K because those with the $50K wouldn't touch it.
