Thanks everyone for the feedback, we appreciate all of the opinions. I'm going to go ahead and roll the "Jetta TDI" into the "Jetta" model on Monday, and make sure that the diesel engine option is set on all of the existing Jetta TDIs.
We won't approve further splits of "x TDI" from other models, and we'll point folks to the
engine filtering feature to view diesels on their own. We could always reconsider this down the road if any one model gets too large to manage on its own, but I don't think we're at that point with Jettas yet.
Thanks again for the thoughtful discussion.
