Tissue,Kleenex. Suzuki, Jeep.
If you look at the whole jeep line, they had a pickup and a grand wagoneer etc. I like to think of the jeepy looking things whether it a willys, samurai, sidekick, old toyota (the jeepy looking one), or any other jeepy looking vehicle as a jeep. Maybe even, in this case, the little jeep. It's simpler and if referred too as a jeep, it takes only one syllable. Ha ha!
In most cases, if someone calls it a jeep, they don't mean it as an insult or a compliment. Therefore I take it as neither, just what it is. Your friend is just trying to give you a hard time. I would let it go in one ear and out the other.
