Why is it so hard to buy parts from people

Buying used online is convenient but swap meets are the way to go. You meet the seller face to face and you get to examine the parts and deal on the spot. There is cost involved but if you treat the show/swap as a mini vacation it is pretty reasonable entertainment. (and lots of fun) Get together with other Mopar guys in your area and split the costs. In years past I have made some Mopar nats trips that only cost me a few hundred dollars. Split 4 ways even $5/gallon gas is only $1.25 each.
