Tether Cars range all over the place... The mite cars are smaller and are relatively cheaper. The size ‘60’ cars, which are larger, like the Rexner, range from $1000 up towards several thousand dollars. Again this is pending rarity and condition. As raced, untouched cars , can fetch some serious $$$$$. As like everything, it’s what someone will pay.
Cali-chopper, I'm assuming the beautifully crafted cabin car and Rexner are scratch built and not restored original cars. You and your dad do stunning work. Mick
