Custom built by myself. I am going to be building custom ho slot cars and trucks to sell along with some custom hot wheels sizzlers and other stuff, So keep watching to see what shows up in my auctions. I take pride in my work so dont worry. You will be happy with purchase! You can go green with this one. Ha Ha! Tesla semi is mounted on a stock Tyco US-1 chassis. Silver color. The lower silver part of body is cast the rest is plastic. Has interior which is hard to see because of tinted windows. Body clips on chassis like original but is not as secure as the standard body, so I added a jag hobby screw in guide pin. So if you want to remove body you will need to buy a tool from them. This truck will preform like any other us1 truck. Chassis has been cleaned and oiled. Also comes with new rear tires. Took a lot of time to get it done. Trailer is not part of auction. Used to show scale. Any questions please ask. Support our troops and first responders.
