Yeah, and the single rear wheel means no normal tow truck, either. Has to be a flatbed.
So the real complaint is probably something like "dealership won't release the trike to be illegally ridden away without a license plate or insurance and they won't pay for a flatbed tow of the unlicensed and uninsured vehicle".
Can't say I blame them. And they're probably going to start charging storage fees for not getting it out of there, too. And ... Can't say I blame them.
