Renting a car can be a minefield with hidden costs and unfair charges adding up to give the customer a hefty bill.

Eagle-eyed renters are aware they have to double-check the hire agreement so they don't get stung by any hidden extras.

But it is just as important to check the vehicle itself.

Renting is one option

One of the most common ways drivers get stung by car rental companies is damage to the car.

That annoying bit where you quickly look around the car is so important.But many renters decide the car looks fine and drives away.

This often ends up with the clients getting back to the rental company to find they've been charged for scratches and dents that had nothing to do with them.

So where should you check?Where are the areas most and least likely to be damaged?
