I would definitely have someone go look at it for you.

Do not choose a PPI shop that is connected to the dealer.

Here's an idea: even if you are planning to pay cash. Use a company like J J Best to get a loan and pay it right off. J J Best sends an inspector out to look at it. We looked at a GT40 and chose to walk away after the seller wouldn't crank it for the inspector. The inspector will not do a PPI. They only look to see if the car is accurately described. We bought the 930 sight unseen this way.

Hagerty's did an article this month on this exact thing. Their advice:

Go See It
Hire a Stand In
Photos and More Photos
Research VIN, car's past, etc.-if it's a collectible car the previous owner will have been on a forum

Good luck!
