Can echo the dreamer and croc.
Bought the Cortina out of Louisiana without a ppe off Craigslist. I sent a check to the seller, who was cool enough to wait.
The 7 I also bought sight unseen from the UK. I was in Alaska at the time and couldn't schedule time right away to see the car. I sent 250 as a sign of interest. The sellers were actually fantastic to work with- connecting over whatsapp from the arctic circle and really doing their best to show me the car in video etc. I had a friend in Ireland fly over to confirm the car in person too.
Both times, I bought cars from low volume dealers. They each had about 8 cars or so in their inventory. The online places which show a lot of cars are sometimes too good to be true.
Shipping was a bit different. For the Cortina, I used uship, which farmed out to a rando. It wasn't the best, but it worked. Paid after the car was delivered. International shipping was prepaid, got the car from the dealership in the UK to the port in NJ. I just drove it home from the port. International shipping included insurance for roro, if you use a crate, I'm not sure.
Either way when you buy remote, you'll be sending money to a stranger. You can do everything and still get scammed. If it's a lot of money and you have time off you can take, it may make sense to fly out to the car.
