No one really calls it that, I used the terminology merely to separate it from 4x4.

That does make good sense, and I happen to like that term, 2x4. Though calling it that might confuse some for a plank of 2x4 wood. In that case, it makes even more sense to say, "Hey, like my 2x4? "... wink wink 😉

Lol, I can't imagine how salty a salesman would be if you totalled their brand new Defender! I guess the test-drive wasn't too much of a success, though the Land Cruiser is a mighty fine vehicle. Just don't let Grouchy anywhere near it. He might treat it like an Arab, for all we know...

P.S. That Defender crash is a teaser from the upcoming Bond film. Expect more Landies getting totalled by baddies.
