Once you have collected all the derelicts you will be able to buy them from the store. So in your case the C10 will appear at the off road dealership immediately after you have collected each of the derelicts.
Like it says, you have find and assemble all five derelict cars before you can buy any of them. I already told you this on my previous post.
- Mustang
- Bel Air
- Beetle
- C10
- Fairlady
Before you have assembled all of these five cars you cannot buy any of them from the dealership. Once you have assembled all of them your off road C10 will be unlocked at the off road dealership.
