he can claim whatever himself is, but he is not an expert

The highlander is sold as SUV, which is expected to have better off-road perform, but it fails to climb a NORMAL slope.

All sedans and SUVs with front wheel drive can climb the hill except the highlander, again, it's sold as SUV, did Toyota re-defined the world?

"Make that slope 5% steeper then no one can get up"
There are two slopes in the hill, and one is 5% steeper than the other one, highlander can climb neither, so his claim "Do you understand that the difference is small" is bullshit.

"- Make that slope 5% steeper then no one can get up"
Just a pure claim by a so-called expert without any evidence.
