The Hellenbach GT is a two-door coupe that resembles a 1967-1970 Mercury Cougar, except for minor differences like the single headlights and added turn signals, and the sides are closer to a 1968 – 1970 AMC AMX. While its body design may occasionally include single-tone body colors, the Hellenbach GT may also appear with the hood in a mismatched color, giving the car a "beater" appearance similar to the Clover and the Tampa in Grand Theft Auto: San Andreas.
Despite its appearance, the Hellenbach GT is capable of high speeds and handles well. The Hellenbach has an extremely high top speed, and beats the Banshee and Cheetah on top speed. It also has better handling, and can take more damage before exploding or catching on fire.
The name comes from the phrase "To Hell and back", which most people say about the reliability of their old beaters.
There are three special colors of the vehicle in the raceLow Rider Rumble (white, brilliant red and sky blue). They can be obtained using this trick: Start the race as usual, but remain in the starting line until the end of the race. Wait for the other racers to cross the finish line. Get into the car of your choice and drive it to your safehouse garage. Leave the garage door open and fire a rocket or grenade at the car. You will fail the race by damaging one of your competitors' cars, but it will be repaired once again after the garage door closes. Save as usual.
