The first step to getting some of the rare cars in nitro type is going to chrome web store and typing in tamper monkey or you can use my link: https://chrome.google.com/webstore/search/tampermonkey
Once you have successfully installed tamper monkey you need to go to this link: https://goo.gl/yWgc4V click on nitro type car hack (Its in blue), click on dealership.user.js click RAW. It should redirect you to tampermonkey hit Install. This should give you cool skins. For the free cars click garage.user.js, then click raw it will redirect then hit install. That’s all now you should be able to log onto nitro type and see all the free cars!
Pros:
It works
Its simple
Cons:
Cannot use in real race
