Like most car dealerships, Hardcore 4x4 offers a range of both different vehicles and colors, as follows:-

The Bushmaster - Green - This is a good truck for beginners with the best all round abilities.
Dust Devil - Red - Another truck for novices, fairly fast with good traction.
Ice Breaker - Blue - The Ice Breaker has superb traction ideal for the pack ice track.
Side Winder - Orange - This is the truck with the best suspension, allowing it to cope with the pot holes in the Sun Baked Gulch.
Brimstone - Yellow - This truck has great suspension, but isn't quite as fast as some of the others, ideal for twists and turns in the Devils kitchen.
Rock Hopper - Purple - This trucks excellent traction allows it to cope with the mountains of the high camber pass.
