Considering purchasing this Dart

He's right, you probably cannot build that car for what his is asking. On the other side of the coin, it depends upon how well it was built, if any short cuts were taken, & a host of other gremlins that can show up. I would have a trusted friend with me who isn't enamored with shiny things. A second set of eyes from a friend who will keep you sane before jumping in would be a good idea. I'm not downing the car, I'm just saying "Buyer beware".
