You are right, all KJ Cherokee's come with power folding mirrors.
Although quite handy at times, the motors are quite weak and he mirrors get stuck all the time.
I had a 2002 and have now a 2003 KJ and both had issues with the motors, at the moment only one side moves and I decided to do it by hand from now on.
If you still want them you could get some from Jeep UK (extremely expensive) or you could contact a UK wreckers yard
