I am in the process of buying a used Superformance Cobra.

It is about 700 miles from me. I obviously want to know if the car is sound before I buy it. The owner says it is perfect. I believe him. I don't know him, but I think he is an up front guy (he's probably reading this!!). A mechanic friend of mine has offered to fly with me to see and evaluate the car, but he is not available for a few weeks. I'd like to get it done before then if it makes sense. It has a 351W/ 385 hp SVO crate motor so nothing too exotic.
I change the
oil on my own cars and do a few other maintenance items, but I don't consider myself a "mechanic".
If I see the car and it looks and drives right, would I be a fool to buy it on the spot and drive it home? Is this too big a risk? Should I wait weeks for my friend to fly with me?
I guess the down side risk is I pay a bunch of $ for a car that has problems that I should know about but don't, try to drive it home and get stuck in BFE.
Is this the right forum to ask this?
Thanks,
Jack
