LOL!!!! i'm not laughing at the CNG, i'm laughing at the surf, it's riced out and to top it off he's got some ghetto wiper on the back,... something tells me that it's not even an SSR-G.
as for the CNG, sure why not, but it makes no sense to fit CNG to such a vehicle as the fuel economy will still suck AND you lose your trunk space so it defeats the purpose of having such a vehicle. would have made more sense to have bought a diesel version in the first place.
