Oh mad what a spot!
Though Kaz having a model of a Lotus Esprit Turbo is far from a guarantee of one being added to the actual game, it's of note that it's a different Esprit that was included in the old datamine list:
* esprit_v8_02
Not that the old datamine list contained all of the cars that have been added in updates, nor is it likely that all of the ones in the list will arrive at some point.
Just an interesting observation I thought I'd mention.
Evidently Kaz still has an interest in Lotus, even despite the licensing issues.
