I have a guy at work trying to sell me a HPI Baja 5B, I don't know anything about them. He said it runs and drives fine, no issues. He says it has a weed whacker motor, I still have to google this car but figured this place would have the best answers. He is going to bring it to work in the future so I can check it out, I only have electric RC, anything I should look out for on this specific car?.. you think they are worth $250 used and decent shape? Thanks fellas.
