How do I choose an off-road car?

When choosing an off-road vehicle that suits your needs, consider the following factors:

  • Terrain: Think about the type of terrain you’ll be driving on. Will it be muddy, rocky, or sandy?
  • Vehicle size: Bigger vehicles tend to be better off-road due to their higher clearance and ability to traverse rough terrain. However, smaller cars may have better maneuverability in tighter spaces.
  • Suspension: A vehicle with better suspension will be able to handle rougher terrain better than one without.
  • Traction control: Look for a car with high-quality traction control. This will help you grip the road and stay safe even in difficult conditions.
  • Price: Off-road vehicles can vary widely in price. Determine your budget before beginning your search.
