Avoided disaster today

[Richls5]

I recently sold my 70 ls5 Chevelle and have been looking for a replacement. I found a 70 ls5 phathom blue m22 car 5 hours from home claimed to be original paint and interior matching numbers. I arrived at the car around 8am after leaving home at 2:45 instantly saw the paint was for sure lacquer everything but the door panels was original as well. Vin stamp seemed off but I’m not expert I then checked the casting date I see H 25 70 car was built 4th week of February 1970 I said that’s odd. Look at again I’m for sure 100% seeing H 25 70 the owner has no idea. Get the car on the lift see a large oil plug near the oil filter I said to the owner was this 4 or 2 bolt when you rebuilt the engine? He says 4 I said I’ve seen enough that’s a re stamp he claims there’s no way. I explained it all to him. He understood he was asking 70 I offered 55 he declined said 65. I returned 60 he said 63 is bottom
Dollar. I drove 5 hours home without the car questioning my decision. The only thing it retained was the m22 everything else wasn’t the born with stuff
