I agree it is all relative. If I stil had a one ton around the X5 would not have been called a truck

When I had an X5 and a Z4 at the same time, and there were several other cars in the family, I called it the truck as in "let's take the truck today". All the rest of the time it is referred to as a car here.

If necessary it is called an SUV when referring to luggage capacity.

It is never called an SAV, that is just so lame.
