Had a 2001 BMW 330 with leather and a 2006 Mini Cooper S with leatherette.
The leather showed wear quickly and I had to put seat covers on to keep from destroying the leather.
The leatherette after 6 years looked brand new even though the car sat outside in the Texas sun everyday I owned it.
History as our guide, my new X1 and my wife's x3 were both ordered with leatherette.
