Hi
We are sorry to hear that you are not happy with your model.
The measurements of all of our models are clearly stated on the product page and for future reference, 1:64 scale cars are 1 64th of the size of the real thing, where as a 1:18 is an 18th of the size, therefore.
If you would like to return the model then please do get in contact via our Contact Us section at the bottom of the website page. If you do wish to return it, then full packaging is required as our 1:64 models are collectables, not toys. We will follow up directly with details of how to return the model if this is required.
Kind Regards
