I have friend that has a heavily modded '08 Shelby that pushes 600rwhp at the wheels thats in my Camaro club and he is the coolest guy. Very modest and just overall loves cars. He doesnt wanna run with the local Mustang clubs bc of their pissy attitude so he runs with us. No biggie, I enjoy having him along with 2 Chargers, a Mazda RX7, & an Audi also in my Camaro group. Ill mess with my friends and they do me too but we all can take a joke. Ive posted things similiar to what you posted on fb and my Mustang buddies know Im just joking and dont get upset about it. Who cares
Lifes short, enjoy it.
