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

That would not be legal in the state of Fl. I built wrecks out of a salvage auction for years. Still involves an inspection by FHP and still issued a rebuilt salvage tittle.
Not in texas it isnt, or wasnt until recently. Only requires a regular vehicle inspection by a registered service garage that does motor vehicle inspections. I have repaired and flipped 2 salvage cars myself, however neither of these included swapping any vin numbers, why that would be illegal. It also may be that they were both 1990 daytona ES hatchbacks, 1 was a V6 5 speed , the other a 2.5L automatic, and really who gives a flip about those. It starts with a TX salvage title turned in to the state, and ends with a legit texas blue title.

State recently closed the loophole now though. They will not issue any salvage titles as rebuilders. Once they get wrecked and the insurance companies total them, they go to the salvage yards, vins are put in a database and they are gone forever.

I have 1 last salvage title for a 1988 daytona shelby Z t top intercooled car collecting dust in the corner of my shop. Being that the salvage title was issued in 1999 before the closure of this loophole, fixing it and driving it is still valid under the old law as grandfathered in. and i can repair the car legally. No frame damage, car was never wrecked, just junked very tired with 197,000 on the odo.
