How to tell a honda apart?

im fixin to finance a 96 honda accord through a small dealership and on the back it usually says lx dx or ex and this one didnt. i know it has a moon roof all power with leather interior so to me it seems like the luxury package which i was thinkin its the lx.....is this right? also its a 4 door with a v6. and i was also wonderin if anyone knew what size v6 it is since i didnt get a chance to check tht out on the car and all the car spec sites are sayin four cylinders are in the hondas. plus when i test drove it on the shifter (automatic) it has D4 D3 3 2 1 what is the D4 and D3 for?
