I think there is no reason for Lexus to be absent from the large 2 door market. This version is the SWB (short wheelbase, in old coach-building terms). This would be the base for the Sport version, which would benefit the most from the pillared construction in torsional rigidity etc. Lexus would also market the LWB coupe, a long wheelbase model, with pillarless construction, for higher-end lux sales. Chop to come before its sale date, lol.
One of the minor changes I made was a cutline on the lower rear bumper cap, to match a similar rocker panel groove in the middle of the car. I think it makes the bumper look lower and the rear overhang look longer, which aids in the height/length visual proportion. I also added more obvious LED taillights and modified the chrome plinth molding. A full length glass roof should be standard on all luxury cars these days.
