Not positive, but I'm guessing since it's a "base" car, everything but the shifter and steering wheel will be tex, not leather.

I had a '98 E300, but it was configured a bit differently than the '99. The '98 was all tex, no leather. It was easy to tell the difference. On the tex cars, the upholstered side airbag covers on the doors were smooth, but had a wrinkled, gathered appearance on the leather cars.
