Not the kind of error I was looking for...

I picked up this Camaro from a small hawl recently, I thought it look pretty good until I cracked it opened - like the picture above.

I placed it on the table and released that the car wasn't sitting on all four wheels. When I looked closer, I discovered there was something protruding from the driver's side inner rear fender. What is it? A tumor?

Aw, dang... It's a casting error on the metal body. :(

I guess it will be in this state forever. What should I do with this Camaro?
