No you don't get free spares..

If you purchase the car from an authorized dealer you will have to send in a proof of purchase.
you will get a form sent to you, you fill it out and send it in with the broken part and we will replace it, you have to pay a small shipping charge. but nothing more.

The body is not covered, the parts that are covered are plastic chassis parts (suspension arms bulkheads, c-hubs, ect.)

The warranty is for broken parts, not just worn out parts.
