Some of the parts for the ETK seem too specific for a car that only comes in wagon form, and since the "800 series" consists if only two numbers (854 and 856), there is a seeming implication that we might get a sedan or even a coupe in the future. The devs have made no mention of whether or not we will, but time will tell. We're all playing the waiting game here, and development takes time, so just hang in there and see what unfolds. Worst case scenario is that modders will have to take over and make one. There are talented people here who may decide to do it themselves.
Just my guess on the logic behind the naming 8=trim level or generation 5=form (wagon, saloon, coupe, convertible etc) 4/6= no. Cylinder in the engine. There is no reason not to make a new car that can reuse many existing parts. The devs might be trying to surprise us (hard top convertible that folds the top into the boot, maybe??)
