At this point, if you're interested, you're just going to have to go see the horse. 5 minutes in person is worth a million pictures and videos and "online opinions". You still seem to be dragging your feet on going to see him? You finally found a horse that appears to be the right size, the right price, and not a total whacko according to the video. You've had someone go out to see him in person, they had a great opinion of both him and the seller.....you've gotten videos of it. You are not going to get 20 minute long high quality videos for a $750 craigslist horse. $20,000 hunter pony, yes. The video showed the basics. Nice horse, not crazy, saddle broke. Tolerated "newbie" rider he had never met before. What is "forward" to one person is eager and interested to another. What is friendly to one person is pushy and disrespectful to another. You really just need to see this horse yourself.
Quite honestly, the seller has gone above and beyond to fulfill your requests....she hauled the horse to an indoor arena for a test ride, attempted to send videos, has spoken with you multiple times........and yet you are still "on the fence"? Either you are interested in buying a horse and don't think he is the rightone, or you are interested in "shopping for a horse" without ever actually following through with the sale?
I am surprised he hasn't been snatched up by someone else during this time. I would have been in the truck and on my way as soon as I got a good report about him...if I was really interested in buying a horse.
