Thank you all very much for the answers.
Well, I think, if the car is really good, then he is maybe in the 40's. If I check Hagerty, a car is this price must be Excellent or better.
Important is to identify all numbers to see more details.
The spoilers are not that important for me. I like the rear spoiler. But, yes, it's not original.
The seller told me on the phone it is an all original car. But he also explain me how good the 3 gears shift with the powerglide, but as I know, the powerglide has only 2 gears...
I can't go personally and see the car. Too far away. Yes, it's against all rules to buy a car, but I did it in the past quite often. Lucky me, everything was OK. I can arrange a company who offers PPI to have a little bit more information about the car too or maybe Elroy can help me. In the past Years, I have important some cars from USA to Switzerland for me or for friends. No problem, I know how to handle.
Yes, I agree with you, it doesn't look original under the hood. Hope all original parts are with the car.
The owner told me on the phone it is an original car with matching numbers. But not all people have the same understanding for "original".
Now, I hope to receive more pictures soon.
