I drive a Toyota SUV.
I love SUV's, they have so much uses! In some countries, like the US, SUV's are not classified as cars, but as light trucks
Weird! I love SUV's a lot too! They're great for bumpy roads or for hauling a trailer.
Very handy in big countries like the US. Speaking of hauling, some SUVs have the towing power of a pickup truck with the passenger capacity of a minivan or large sedan! 
I like that they have so many uses, and they make great passenger cars! Are SUVs common in other countries?
Well SUVs overtook lower medium segment cars to become the worlds largest automtive segment in 2015, they do account for 22.9% of global "light vehicle" sales or 36.8% of the worlds "passenger car" market in 2015 
Oh wow. That's pretty recent...Any idea when SUVs first became popular?
I'm not sure actually but i know that in recent years, in some countries the term SUV replaced terms like "jeep" or "land rover" in the popular lexicon as the general description for light 4 wheel drive vehicles
I could see that happening. Jeeps and Land Rovers look a lot like SUVs.
Exactly! The good thing about SUVs is they have an upright build body, taller interior, high seating position, and centre of gravity, and available as all wheel drive for off road capacity or when the weather gets hazardous!
