Range Rover Vs Cadillac Escalade Vs Hummer H2

Lol.

Personally, I don't like either of those cars.

They're way too big and clumsy, called "off roaders", but in reality, how many owners will drive them, even if it rains, for fear of getting their chromed 22" wheels wet?
They're also most likely to overturn, if a sudden evasive manoeuvre is made, centre of gravity's way too high.

The Hummer's wider and lower, so may fare better.

You are right but could be expensive to maintain in Nigeria since few people understand its internal mechanism.
