There were only two trim levels of the Diamante in the United States. They were the ES, which was essentially the base model with a 12 valve SOHC 3.0 liter V6, and the upscale LS, which got a DOHC 3.0 liter V6.

The standard features on the ES include power windows, power mirror's and driver's airbag on all years. Passenger airbag was standard on some of the later models (required by US law). Some optional features include antilock brakes, cruise control, and a sunroof.

The LS came with all of the standard and optional features of the ES minus the sunroof, which was optional along with leather seating. The sunroof was switched from manual to power in 1994, and new options were added like the CD player and traction control.

These cars never seemed to catch on in the United States the same way they did in Japan and Australia. You can still find them on the used car market, but they aren't very common. The best and easiest place to find one is on eBay. It's also a great place to sell used cars and get a huge audience of buyers.
