Buying from afar

I (the buyer) paid the cost of transportation to me, but the seller was responsible for the cost of return transportation if I did not accept the vehicle.
Fortunately, the Dart was as described and also included more parts than had been in the initial description and photos.
When all was said and done, I figured the purchase price covered all of the new parts (including a Mopar crate engine - 380-horsepower 360 small block, freshly rebuilt 727, 8.75 489 rear, new exhaust system, Auto Meter guages, and more) and the car itself was free.
If I were the seller, I would never agree to that. What if the potential buyer was way too picky, and said no based on BS stuff for the price of a car you are talking about. Let's say we are talking about a nice 69 Barracuda Fastback that was accurately advertised as a very nice driver with some flaws with PS, PB, AC and a 340 4 speed for $25K. Then the potential buyer says, "Hey, there are some scratches in the paint and I am not happy with the interior." But you accurately advertised those flaws. Then you are getting stuck with the cost of return shipment.
