Muscle Car

The Muscle Car (sometimes referred to as the jalopy) is a vehicle used by Gordon Freeman and Alyx Vance in Half-Life 2: Episode Two. It appears to be a stripped-down-and-rebuilt 1969 Dodge Charger.

The Muscle Car is an invaluable vehicle in the resistance arsenal. It is used to transport resistance members from outpost to outpost. The Muscle Car has a single passenger seat, allowing for one passenger. Like the Dune Buggy, the Muscle Car is capable of a turbo boost, however the Muscle car's boost is not as fast as the Dune Buggy's boost was, making it much more controllable.

When making sharp turns, the Muscle Car tends to skid. This happens especially on grass or dirt.

Half Life 2: Episode Two
Gordon Freeman and Alyx Vance retrieve the Muscle Car from an abandoned and recently raided resistance outpost overlooking a bridge. They find the Muscle Car, seemingly intact, on the far side of the bridge which is not directly accessible. Gordon makes his way through the zombie infested outpost to retrieve it. The Muscle Car is used until Gordon and Alyx make it to the White Forest Resistance base, picking up a radar module from a still occupied resistance outpost along the way. At White Forest, Mirt makes several changes to it before Gordon uses it against the Combine while defending Magnusson's rocket.

Tactics
Use the Muscle Car to run over zombies and break through barricades. While riding in it, Alyx helps by using her gun to shoot down any enemies. She also seems to take aim more and make more accurate shots.

Unlike the buggy sequence, there aren't any long jumps that need to be made but it can be helpful to use the turbo boost to try and stay ahead of the Hunter-Chopper and during the final battle to get ahead of 'rusher' Striders or ram Hunters (though they often jump out of the way).
