Nothing wrong with doing homework, but admittedly, the OP has more important home projects and it sounds like getting involved with a 50+K old car that needs work is the last thing that he should get into at this time. I'm sure that most everyone here would agree.
If a 70 Bee is what he wants, then he should do some research, ask questions here & talk to owners of other owners at car shows. Most of all, be patient and go see a car in person. DO NOT solely rely on pictures and cell phone videos. Everything can be made to look good in pictures.
A 1970 383 Super Bee is not really a rare car & desirability is subjective oin comparison to other years. But back to this particular car .... Enlarge what few pictures he has in his ebay ad and you can see that the engine compartment & exhaust system both are a complete mess.

Ask yourself why the seller doesn't have much of a description of the car in his ad and notice that what minimal pictures he did supply really don't show much. There's a reason for that & to me, that's a warning that the seller is not very forthcoming, which should be taken as a major red flag.
However, if you're asking him to send pictures and videos to just gain knowledge for yourself, then all you're doing is jerking the seller around.
Well, that's my 2 cents worth of advice. Take it for what it's worth.
