Eastbound and down, loaded up and rockin', we're gonna do what they say can't be done. In this case, with a rough C5 on dirt roads.
If a Corvette Grand Sport can be a rally car, so can a C5 that has seen better days. It might oversteer way too often to be truly successful, but lap times are for nerds anyway.
The C5 is cheap fun, sounds awesome, looks badass, and fiberglass is always cheaper to fix than a complex four-wheel drive system.
Why this isn't a thing yet is beyond me.
