If you have the money, ask if he would take $300 for all three, keep the blaster for yourself, do what ever with the threewheeler, and part out the motor on the buggy, with that motor you could make your money back easily. I would scrap the frame to the buggy, its junk. but you can make about $500 off the VW motors in parts. or get it running and have a good start for a future buggy project.
