VIN 242370Z124865
If you're considering purchasing this car, hook up w/ others here who know these cars better but for starters, the way the description reads seems to indicate the engine is not original to the car?.
Also note that Googling the Vin results in numerous hits of the same vehicle for sale also past attempts on eBay and some past sales/no-sales are in French so it's possibile the car was in Canada?.
If by chance the car was delivered new in Canada, more docs would be available from GM Canada Vintage Services besides the PHS docs..
Good luck!.
