Anyone who uses body codes tends to be a jeeper. Sj, CJ, DJ, wk, tj, xj, jk, these are all things that people who have had a Jeep and know that wrangler isn't a Toyota. Not everyone is an enthusiast. I'm pretty sure in most countries outside the US, pretty much any 4x4 SUV that isn't a range rover is referred to as a Jeep. It's a type of vehicle, not the name of a brand.
